I've enjoyed reading the comments on Fred Wilson's blog much more since he implemented disqus. Maybe we can get Arrington to implement disqus as well so I don't have to read any more comments from Fake Steve Balmer.
I take that back. I thought this was about a clickable logo in general--not about the homepage specifically.
I guess it is ok to not have the logo linking to the homepage from the homepage itself. (Though there are certain sites that I like to have open and click on the logo to refresh the content.)
Yep, the background color. It's a little dull, but that's just my personal preference. So I don't know what other feedback you've gotten, but take what I say with a grain of salt.
EDIT:
Also on pages like this one: http://disqus.com/people/danielha the text of the comment and the box on the right (points, replies) overlap sometimes. Minor quirk, but work getting fixed.
And you might want to make the green arrow (on hover) a bit more noticeable... kinda like the red arrow for voting down.
Sorry for all the cosmetic feedback, but I haven't gotten around to creating an account to give technical feedback/bugs.
It's definitely very cool, and useful. Something I can't live without? Certainly not. Still, I think the idea was well-implemented and wonderfully executed.
