It could mean she's interested ..... hehehe.......
Absolutely nothing. It's just to get their attention.
There is not a feature to stop people from poking you on Facebook.
Not really. Poking has no real value until a friend request is made.
Someone is trying to get your attention, poking on facebook is like sending a ping on blackberry or a nudge on MSN (if you have ever used MSN you will know what i mean) its basically just someone trying to grab your attention, by poking someone back your usually provoking them. You shouldnt usually poke anyone back that you dont know.
It is simply just a poke, a fun little feature on facebook where people exchange pokes. If alot of people are poking you it is a sign that alot of people like you as a friend or colleague.
Poking somebody anywhere is dangerous. The navel is not especially sensitive.
Poking them with a fork.
YES
Well it depends, if you like someone you might be poking them to get their attention, but if they are your friend you might just be poking them to cheer them up or tease them.
He either likes you or is trying to annoy you.
no
