Yes, I have worked on Connectiyo before... This time it's not going to be an all-in-one website, in fact, it's going to be exactly the opposite of that; It'll barely store any data, here's how it'll work (I think I've blogged about this before):
There are so many social websites today, each has its own profile, status, info, etc... There are websites that try to put them all in one place but they end up adding to the mess rather than fix it; they all have "what are you doing" and their own profile.
Connectiyo is different; it won't store any data of its own, it won't even have its own accounts: It'll use facebook connect.
It will allow you to gather all your contacts from everywhere (Yahoo, Google, facebook, twitter, etc) all in one place, merge the same contacts, eventually, you'll everything you need to communicate with your friends in one place, and the cool thing is that, unlike similar services, they don't have to use the site for you to see their updates.
I really think this'll work out 'cause I actually have a problem to solve unlike before.
I started designing the interface, and I started reading about using facebook's API with Flex, however, I still need to finish my final project (final changes), after that I'll be free to work on Connectiyo, I might even start a blog about it (Yey!).
PS: I had to choose between this project and another crazy idea I have. I might blog about that one soon.
God bless you all!
