I like it
I still see some missing spaces

-- at "MesFavs", "Spurl", "del.icio.us" and "Netscape". I know, I'm picky. But I tend to pick up on that and it always bothers me
I hate giving you advice on this since I know you already know all of what I'm going to say, but anyway -- it looks like you have your lists hard coded, perhaps even in HTML (missing spaces here / there). As a programmer, I've learned that anything done more than twice deserves to be put into a "loop" and not done manually. I would propose that you put the URLs, the icons and the names into arrays and let the PHP page put them together properly. That way you can just add new services, update URLs or names, move them up / down programatically. Run tests - move a random service from the bottom up top, etc -- no HTML coding involved, just change a number in the code or better yet, in the database.
Something else that ... bothers me ... but won't bug any normal user: you're using rel=nofollows to link and it's highlighting the links in my browser (you probably have the same installed, which SEO-geek doesn't

). You're already blocking the page from being indexed, you don't need those rel=nofollows in there.
If you want to leave them there, I suggest one of the following:
1. Build the links with javascript (kind of iffy....)
2. Code with rel=nofollow but use javascript to remove them as the page is loaded (kind of sneaky)
3. Just use normal links and make sure that search engines can really never read the page (ie check user-agent/IP and return 500 for them)
I would do the last -- or the second if you feel sneaky. It's easy to add an onload-handler that will go through the links and remove the rel=nofollow attribute on the fly, that will make the links look straight but they'll still be blocked. On the other hand, maybe that's just going tooo far

- just drop the nofollows.
The rel=nofollow is something that only a handful of the users will ever notice, but the SEO types are sometimes responsible to implement your script on their sites and they might be worried about something like that if it always highlights in pink with a red dotted border (at least that's my setting). Also, you never know when a browser like Firefox will start highlighting nofollow'ed links by default: to show the user that those links are not to be trusted (if I had my way, that's what it would be doing, but that's another subject).
One thing I'm also not so sure about ... is the design of the logo text/graphic ... it looks very "simplicic", it seems (to me -- as an absolute non-designer) to be lacking a bit of polish, a dash of "power". I really can't put it into words (and again, I am an engineer not a designer

).
I hope it helps! I really like the new design!

PS any reason you're not including Slashdot?
PPS how about a simple way for the users to suggest other "social" sites? That way they would keep you informed instead of you having to notice that there are new sites out there. Perhaps a last link with "Your favorite site" that leads to a feedback form.
