How Much Is a Site Worth?

stonysleep.com has been running for a while (10 or 11 years I think), admittedly not in blog form for all that time.

How Cool is that!?! Though am a little surprised what’s happened in that time to cause that. Perhaps google has finally got round to indexing all the blog so put a higher pricetag on it.
Anyways, check it out i you have a website or are curious how much some of the more well known sites are worth
