Do you wonder what those little icons above are? If you do, you are missing out on a great opportunity to market your website. Below is a list of the more popular social bookmarking sites and their own description of themselves. Visit some of the sites and decide if your site might appeal to those users. We can help you add social bookmarking icons to your site, to make it easier for visitors to bookmark your site.

BlinkList - Make lists & share with others! Or keep em' private. Save websites for reference, research, or for fun! Read those sites later! When you have the time. Have them appear in your links on your blog instantly!

Blogmarks - BlogMarks is a collaborative link management project based on sharing and key-word tagging. Build on a blog basis, BlogMarks is an open and free technology. Now, you can access your favorite URL's from any computer. And with BlogMarks, you share your favorite with other users.

Connotea - Connotea discontinued in March 2013. Free online reference management for all researchers, clinicians and scientists.

del.icio.us - On June 1, 2017, Delicious was acquired by Pinboard, and the bookmarking service was discontinued in favor of Pinboard's paid subscription-based service. As of August 2019, the site is inactive. del.icio.us was a social bookmarking website -- the primary use of del.icio.us was to store your bookmarks online, which allowed you to access the same bookmarks from any computer and add bookmarks from anywhere. On del.icio.us, you could use tags to organize and remember your bookmarks, which was a much more flexible system than folders.

De.lirio.us - In 2010, De.Lirio.us was acquired by Reuters and ceased operation as a social bookmarking site in April of that year. The intent was to build a customized search engine for every ZIP Code in the US, that's over 40,000 search engines. Each one would favor websites that are either local or serve the area. This should have given great results when looking for local services, information or products.

Digg - Digg is a place for people to discover and share content from anywhere on the web. From the biggest online destinations to the most obscure blog, Digg surfaces the best stuff as voted on by our users. You won’t find editors at Digg – we’re here to provide a place where people can collectively determine the value of content and we’re changing the way people consume information online.

diigo Diigo is a powerful research tool and a knowledge-sharing community

facebook - Facebook is a social utility that connects people with friends and others who work, study and live around them. People use Facebook to keep up with friends, upload an unlimited number of photos, share links and videos, and learn more about the people they meet.

folkd - The idea is to aggregate recommendations, tags (keywords), audio records, comments or just "more information" which exists within knowledge of the people (the folks!) and connect it to particular web pages or topics. You and other folkd users will use this additional information while surfing to discover the web faster and find things you'd probably have missed otherwise.

Furl - Furl was purchased by Diigo in March 2009. Furl was a free service that saved the important items you found on the Web and enabled you to quickly find them again. Furl archived a personal copy of every page you saved. When you wanted to recall it, you could find it instantly by searching the full text of your archived items. Each member had a personal archive of 5 gigabytes (GB), large enough to store tens of thousands of searchable items.

LinkaGoGo - The goal for creating the linkaGoGo service was to make it so fast, feature-rich and customizable that people would consider it making their home page. To achieve this goal we designed it from the ground-up to be fast enough to rival the native bookmark lookup in a browser. Our turbo mode is an example of such design. We added a lot of features by using it ourselves a lot (hence the link reminder feature) and listening carefully (we answer within 24 hours) to the need of our members (therefor we support now more then 7 different browser bookmark formats).

Ma.gnolia - At Ma.gnolia, members save websites as bookmarks, just like in their browser. Except with a twist: they also “tag” them, assigning labels that make them easy to find again. So when you search for something, you use words that people choose and look only at websites that people think are worth saving. Suddenly you have access to a human-organized bookmark collection that numbers in the millions, but is as easy to use as a search engine.

Netvouz - Netvouz is a social bookmarking service that allows you to save your favorite links online and access them from any computer, wherever you are. Organize your bookmarks in folders and tag each bookmark with keywords. Access them quickly on your own personalized bookmarks page.

NewsVine - Newsvine's primary purpose is to provide a place for people to share and discuss topics relating to the news.

Reddit - reddit is a source for what's new and popular on the web -- personalized for you. Your votes train a filter, so let reddit know what you liked and disliked, because you'll begin to be recommended links filtered to your tastes. All of the content on reddit is submitted and voted on by users like you.

SlashDot - News for Nerds. Stuff that Matters.

StumbleUpon - StumbleUpon helps you discover and share great websites. We deliver high-quality pages matched to your personal preferences. These pages have been explicitly recommended by your friends or one of millions of other web surfers with interests similar to you. Rating the sites you like automatically shares them with like-minded people – and helps you discover great sites your friends recommend.

Technorati - Currently tracking 112.8 million blogs and over 250 million pieces of tagged social media. Technorati is the recognized authority on what's happening on the World Live Web, right now. The Live Web is the dynamic and always-updating portion of the Web.

Wists - Wists appears to be closed down. Wists was created for 2 simple purposes: 1-To make finding well designed, interesting or unusual products and collectibles both simple and fun. 2-To make publishing or sharing lists of recommendations and wish lists easier and more appealing than maintaining a weblog and not tied to one particular store.
