According to Wikipedia;
Social bookmarking is a method for Internet users to organize, store, manage and search for bookmarks of resources online. Unlike file sharing, the resources themselves aren’t shared, merely bookmarks that reference them.
Sites such as the following do this in some different and occasionally unique ways.
*indicates I have personally used these sites.
Social bookmarking sites attract different people who have different interests. For instance, I like Pearltrees (a lot) and StumbleUpon, but just cannot seem to get myself interested in Diggs or Reddit. There is nothing wrong with this. It is just how we are wired. Every site is not for everyone.
Again, according to Wikipedia:
For users, social bookmarking can be useful as a way to access a consolidated set of bookmarks from various computers, organize large numbers of bookmarks, and share bookmarks with contacts.
Pearltrees. I know for myself, if not for Pearltrees a few months ago, when my PC crashed totally, I would have had no idea what bookmarks I had, as my favorites were wiped out by having to completely install a new hard disk. With Pearltrees, I was able to get a large number of my bookmarks back. One of the reasons that these are now called Social Bookmarks is that the sites offers you the ability to make them public to others. I have allowed this with Pearltrees and by doing so have run across some “Pearls” by others that were very helpful for me in learning about Writing, Reviewing and much more. While I have been in Canada, with my husband, I was able to find many of my writing favorites by going to Pearltrees and logging in. This makes it very convenient when you are using someone else’s computer and don’t have direct access to your computers saved bookmarks.
StumbleUpon is another that has a rather unique way of saving bookmarks. You have a “toolbar” that allows you to “Like” or “Dislike” a page. When you “like” the page, it is added to your favorites, which is then saved to your user profile with StumbleUpon. When you “dislike” a page, it remembers it, to try to not show you pages that are similar to the ones you have disliked. Also, when disliking, you can indicate if the page is a duplicate of one from earlier, spam, or simply isn’t what you like. This helps to make StumbleUpon a good tool. Just recently, I used StumbleUpon to go through Blogger blogs only. I found a number of very good ones to favorite, and some to just go on by. I’ll admit, I rarely dislike something unless it is really bad.
Fark is…what can one say. I’ll allow the FARK F.A.Q.to answer what FARK is:
The first thing you should know is that Fark.com isn’t a Weblog. Fark.com, the Web site, is a news aggregator and an edited social networking news site. Every day Fark receives 2,000 or so news submissions from its readership, from which we hand-pick the funny and weird notable news — and not-news — of the day.
Sadly, some people have devised a way to actually abuse the Social Bookmarking. They will bookmark the same site over and over, causing the Search Engines to list it as a popular site. This is not only an abuse of the Social Bookmarking, but also of Search Engine Optimization. (SEO). Developers of these bookmarking sites continue to be vigilant and to update their security measures to try to stay ahead of these abuses.
It is well worth your time to sign up for one of the social bookmarking sites that is listed above. If something happens to your computer, you will have a way to at least get the majority, if not all of your favorites back. Also, you can perhaps find something you like on someone else’s bookmarks. Maybe make new friend, or find something new to write, create, etc.
