The problem:
The social networking / Web2.0 services world might be intimidating for someone who has no personal presence on the Web (your grandma), or maybe just has a meager Facebook or MySpace page. FriendFeed and others do a good job of managing the diverse services/accounts, but you still have to create accounts and set up your profiles individually. You may not know what accounts you need or want (do I need a Twitter account?) or what each service does differently (e.g. digg vs. delicious vs. stumbleupon). You ask newbie questions like, how do I get a blog up and running? which blog site is the best?

And seriously, there are a ton of services out there:

The solution:
The idea is to have a wizard-like portal that guides a newbie through creating his/her Web presence. You learn a little bit about the user, what they want to do (write a blog, share pictures, post status updates, all of the above) and you create the right accounts for them and give them little demos. The key is to make it uber user-friendly. At the end it can direct them to sites like FriendFeed et. al. for managing the variety of accounts the wizard just created for them.

I'll admit, I have no idea how to monetize this. You probably don't want ads because that would distract the user during the process (maybe they'd be ok at the end). I suppose you could charge $1 for the service and people might pay it (at the end). Dunno.

My bad if this already exists somewhere (please share!) Thoughts?
