Unreadable is a bit of an overstatement. Yes there are better fonts out there, but for now I’ve gone with Helvetica until I find something else.
I disagree but good luck with your site!
I’ll experiment with Benton Sans this week when I sit down and work on my site.
Great. I think you’ll enjoy it. It’s from Webtype (really high quality webfonts). You can test them before purchasing.
Note: I agree with you that the comment font size on that blog is a bit too small to read but the article font-size is fine.
