Well I don't notice a difference, sorry.
The "look" of this site is first-rate, easy to use, and seems to work fairly well (not perfectly) with Firefox.
I appreciate how fast the forum is, too. From home here, I've got a 6 Mbit cable connection, and your website is blazingly fast (usually)
Can't say that about all forums I visit.
And another thing: I like how this place is organized, very sensible IMHO.
Keep up the good work.
