BarrenPneuma: If you are uncertain as to whether or not you could commit to any relationship then why bother?
Of course take your time but in doing so ensure that whomever has been drawn to you knows exactly where you stand on these issues. Perhaps you need more time- make it clear. Perhaps you can never truly be involved with anyone but yourself- be honest.
Will NEVER happen on order, Mark!
Leave alone those who does it purely for the "fun"

of it - you surely realize there are many: here and in RL.
Leave alone
predators of all kinds who won't even bother reading it.
Now, about other's:
what comes to my mind now -
this cute redhead (don't remember her name) who a few months ago shared her story and asked as all for advice. The guy she misled was about to sue her

and she was scared. Remember her crooked story?
They both got emotionally attached to each other but her low self-esteem and fear of rejection caused her to make up stories she couldn't "un-make" in order to meet him?
Anyways - it's up to us here and in RL to be cautious, alert, and to take our digital relationships/friendships onto the next level (move it into real world) asap.
That or not taking chances at all
