Thanks to [1] Paul Drago of Perfomancing, I finally have a good breakdown/ list of the common and popular Social Bookmarking sites available (I added the URL links):

1) [2] del.icio.us – strangely enough this is the site I am the least familiar with. It is pretty straight forward but until recently was mainly focused on technology and technological issues– apparently they have expanded beyond that now. The system is fairly strict– don’t try setting up 10 account on the same IP and voting yourself to the top– they will be on it rather quickly. Also, the frontpage is controlled. (If by editors or by friend groups has never really been determined but the top posted contribute the majority of the posts on the front page.)

2) [3] Digg — Digg also amazingly started as a tech geek site as it still primarily focused at that group. Digg’s user base seems to be about the same people that you will find on myspace– a young somewhat savvy audience– again something like 60% of the posts on the front page are from the top 10 users– so the system is rather difficult to break into.

3) [4] Spurl.net – While it isn’t my intention to “rip on” any one site it seems to me that Spurl is completely over run with spam– the things that make it to the top “hot sites” seem to be garbage. I may be wrong about this but there doesn’t seem to be any sort of commenting system which makes other sites so appealing. .Commenting is a major part of social networking.

4) [5] Wists.com is a social shopping bookmark site– it allows you to simply and easily create adds– so easy in fact that the entire page is flooded with ebay ads. I don’t know if real people even use this site.

5) [6] Simpy.com — while the site is pretty basic looking it lacks a major feature that seems to have eluded this social bookmarking sits and their quest for stickiness: comments. Also, from judging traffic stats it seems to be a site over-run by spam.

6) [7] Newsvine.com – This is probably my second favorite social bookmarking site. The layout is professional and clean- it is probably the future of social bookmarking as it reaches mainstream audiences. They are very much again the self-promotion of your site and will flag you site fairly quickly if you submit yourself to it. It has pictures (which is rare on these sites) it also looks like a professional news site. Fairly popular with a older (and rather political crowd) I can see FoxNews purchasing this site for some reason.

7) [8] BlinkList.com — fairly nice looking site. Again, I don’t know how many actual people use it– it is essentially a digg rip off stealing pretty much the entire layout.

8) [9] Reddit.com — If I had to guess I’d say eventually reddit (if it stays about where it is now and doesn’t draw too much of a crowd) will probably be the next “slash-dot” (*note: I don’t mean this in a replace slash-dot kind of way but the same sort of people will be attracted here) Very web savvy. They don’t click ads. Which is actually a strong discouragement for spammers. If a mod/editor votes your story down to a zero it disappears. They are after a very specific kind of news (and other fun stuff)

9) [10] Blogmarks.net — Blog bookmarks mainly for developers (web 2.0ish developers at that)

10) [11] Ma.Gnolia — uses a tag cloud– isn’t the easiest site to navigate, has a few “featured” writers but overall it just doesn’t have the same appeal or stickiness as the others. The Usability is a big factor in this.

11) [12] Netscape.com — the front page is controlled by editors. They want to pay top diggers to dig on their site. The site has a huge volume of hits everyday but I would like to see the bounce rate and I am just not sure social bookmarking will appeal to the average person using netscape.com as the default homepage for at least 2 more years.

Do you have any to contribute to the list? Don’t hesitate to put it in the comments. I would be interested to check it out.
