#2. DON’T POKE HER
Would you ever poke a strange woman in real life in order to get her attention? So don’t do it online. It’s not flirty. In fact, women think it means you’re too much of a wuss to actually say hello.
#3. DON’T MAKE A NUISANCE OF YOURSELF
If she isn’t responding to your private message, instant message — never IM someone you haven’t contacted before — or wall comment, don’t keep bugging her. Let her respond to you.
#4. ASSUME THAT EVERYONE SHE KNOWS IS ON FACEBOOK
We mean everyone — her grandmother, her niece, her boss. This means you can’t write something inappropriate on her wall or tag her in an incriminating picture. If you embarrass her in front of important people, you can kiss your chances with her goodbye.
