Help Please: Super web 2.0 properties examples

Hi All

In soon I will build a website and launch( it may take 30 days) it's related some programming language guides.

So before that I want to build few web 2.0 properties and get them indexed.

But don't know how the best and workable web 2.0 looks like. So someone please share here or PM few realtime web 2.0 properties for purely for my understanding.

And once after building web 2.0 property can I directly use some bhw market place service and blast with GSA links or Xrumer links for building authority to my web 2.0 property.

Note: I don't want copy anybody's money ideas. This thread is purely for building a good web 2.0 property which provides some link juice to my upcoming website.

Please suggest

Can someone please help me

Search this forum for web 2.0 and you'll find enough posts that will keep you busy for the next couple of days. What works for someone may not work for you, so test it, test, and test. I'm not posting any examples because that would be repeating what others have already said.
