This is a non-techie site, with a good cross-section of people. (I mention the nature of the site to prove it is so).
I would suggest your site is visited by people more on the techie side. In comparison my stats would be the complete opposite and is a site that your average homeowner is more inclined to visit, IE7 is about 60% , IE6 about 20%. FF and the rest fill out the other 20%. Those are probably the type of stats you're going to see on most sites with the exception of FF having a slightly higher presence.
Edit: Just looked at the public stats on a very popular video forum I visit frequently where your average user is inclined to be on the technical side. IE60% , FF30%. No distinction on there between IE versions.
