Don't take this the wrong way, just constructive criticism:
1) The logo is plain as hell, try and spruce it up a little (

2) Liven up the design, it is really plain and not much happening, I highly suggest you fill the dead space. No website should have this much space. (

3) Within your profiles, try and bring the users info and details up above the news feed as that is the first thing you should see on a profile. (

4) I don't know weather its an open source script or you had it made fully customised, but try and make things come alive.
5) Domain Sucks, end of. If your serious about making a half decent social network then you need to get a good domain. For example, you look at twitter, facebook, bebo...etc. they have brand-able names, my-info.biz is not really brand-able.
Good luck with your site,
