I noticed the new homepage this morning when I logged in. It looks much more professional than the old one. It seems others must think so too because I got four new referrals overnite and one has upgraded! Cha ching!
Yes, the new design is better than the old one, which doesn´t look too serious to me.
Btw, where did you get your referrals from? I think 4 new referrals isn´t that bad (especially when they upgrade their accounts).
