This is definitely not the first example you want to show in your homepage, if the purpose of your site is to help with personal relations.
The intent of the site is good. I think there will be a big market for this kind of thing if you find a way to help.
An address book is good; just lose the my.peeps name and call it an address book. People are not eager to learn new fancy names for things.
Reminders about relevant events (birthdays, anniversaries) is good.
Of course there is plenty of software around that provides address book and calendar functionality, so these can't be your selling features. Semirandom reminders to do something special? OK, a bit mechanical, but I guess they help.
I'm not sure about the functionality you offer, but anyway I don't think functionality is what matters the most here. I think you want to look for community features. Somehow encourage your customers to ask for and share tips. The value of your site will not come from functionality, but from becoming a hub for people interested in these matters. IMO, if you achieve that, you're golden.
A minor one: lose the "best viewed with" tag. That's so 90's :). People aren't going to get a different browser to go to your site; if your site doesn't work on their browser, they're just going away. Alien logos are noise and cheapen the feel of your site. Don't let any in, unless there is some serious business motivation for it.
