What is HOSTING 2.0 , what does it actually means? what is the difference between normal and 2.0 hosting?
A:
Hosting 2.0 is supposed to be hosting services that support Web 2.0 technologies like Ajax, Mashups and social networking APIs.
The truth is that every decent host provides support for the technologies under them. So unless you want to do something not so common (like Erlang web interfaces) you wont have a problem with 99% of the hosting services around.
