That's my point. So you know what is web 2.0 then! Does samducker's logo fits into that category as you mention earlier his logo is "very web 2.0"...
I don't think so! He must work "harder" to make the thing as a "web 2.0" logo. Currently it's just look like a simple graphic with less "web 2.0" effect, "non modern, non 90'sish/2000ish logo" as you say...
No offense there sanducker Consider them as a positive critique to your logo!

Cheers...
