i've made a few K with this one, its my oldest blog. gets about 700-1000 uniques a day. lots of google image traffic tho. makes a around 4 or 5 signups a week and also some steady supplimental $$ from online dating (i am using a kickass dating program).

I have a few others that have done/are doing pretty well too and a bunch of newer ones that have made anything from $0 to a few hundred. in a few weeks i'm gonna launch some more and just keep building.. blogging pays off in the end. i'm by no means a blog guru or expert.. I still have a lot to learn and have to find more time to update my blogs. I only handwrite, I don't really splog.
