most of my blogs are largely, slightly modified default themes.
boogie-blog.com is 3column kubrik, tailored a little
and most of my other blogs are variations of that theme or the default. I think it CAN look ok 8)
but, having some definition and character to your blogs is really important, I concur.
every day I say i'll find someone to revamp boogie-blog to a better look and feel and every day i put it off
but basic default = NO
