Is that a screenshot from a website, etc? If so, just post the website. Someone will probably be able to find it in the CSS or font tag.
Hm, we'll Im a Mac guy now, but I just tried the font and that looks pretty dang close. Its EXTREMELY easy to read and very pleasing on the eyes and Id like to use it in a start-up blog (incase you were wondering). Thanks for the help and green rep added.
no problems... i think there is a similar version of the font that comes with osx as well (im not on my mac now to check). good luck with the rest of the site design
You have this very interesting tool that enables people to find the font with a pic. Might be worth the try...
