Facebook has the power to destroy a relationship. Fact. Well, a potential one anyway.
The fact that the site actually has a term, 'Facebook stalking', is creepy enough. You're having a chat with someone, you ask what they're up to and you get the response: "Not much really, having a quick Facebook stalk and then I'll get in the bath."
AT LEAST subconsciously, you must be questioning when it became socially okay to declare your prying on strangers profiles publicly.
The worst part by far has got to be when you're in a bar, you look around and see Sally who you technically actually don't know, but you know she's got a boyfriend who she's just celebrated her 12 hour relationship with and she loves going to the cinema on Wednesdays and her mum calls her Sweetiepie Sally.
You know too much. And you don't know her. That's bad enough as it is...
...Let's just hope you're not one of those who forgets that Sally doesn't actually don't know you, because she hasn't spent hours stalking your virtual life, and you ask "Hey Sal, how was the cinny on Wed?" -- n.b. at this point, she either walks away - which realistically is probably the most desired situation for you - or she, rather awkwardly, asks how on earth you knew she was at the cinema - and for heaven's sake just make out you were there too! No one publicly confesses to this shit!
It's the same when it comes to boys/potential romantic interests (PRIs) though. Too much trawling, and you think you know them before you actually do. At least give him/her a chance to defend themselves against that hideous photo you found!
I think that right now there's a strong risk of excessive Facebook stalking either:
a) putting off you eventually meeting because there's no desire to 'get to know' them
b) putting you off them altogether - oops.
The fun of meeting people is about starting from scratch and building relationships, but Facebook gives you this weird one up from the start, and it can turn out to be one of the best platforms ...or the shockingly worst.
