This is a dilemma we've been facing for quite some time now. Different people like different kinds of logos. The logos you see on our home page seemed good to a few people we talked with and the logos I am posting on twitter are all chosen by me. I might just go ahead and replace them with the twitter logos. Thanks for this feedback. No one has previously told me that they didn't like the logos on the homepage. I'm definitely going to consider changing them.
I wonder if it's not just the logos but the layout/design of the home page. Maybe the logos look better in isolation (as on the twitter feed), then all together with their edges jammed together? Maybe they'd look better on the home page with some separation/margin between them?
I dunno, you should probably get more feedback than two random people on the internet!
