important to the surfer? absolutely not!
but after a careful scientific research I found out that blogs with original text get more Google traffic than the rest (all things being equal)
here, see for yourself:

that's basically thumbloger blogs with public stats, check the ones that get the mopst traffic, and copy their model ;)
use your own domains though, I'm still pissed off about the gazillion sites I used to have on free hosts, sooner or later the free blog hosts will die too and lotsa people will get "burned"
