One of my girl mates- (who, for the record's a singer and a bloody good one), often performs live gigs on sites like Facebook and Tinychat- (which, if anyone don't know, is pretty similar to Skype!) I've watched a few of these gigs of hers and she's, quite frankly, bloody amazing at what she does....
If you’ve got a good voice and want to express it by using a social media platform, go ahead. It maybe a really efficient way of getting noticed and decent paying gigs, who knows unless you try it? Your mates won’t be laughing, they’ll be jealous if you make a success of it. Choose a decent song though, one that’ll suit your voice.
The only silliness is calling wanking at home a "gig."
Mate, you’ve gotta do what your heart tells you. I’m sure you’ll be great and be glad you did it.
You're not going to be singing soprano, are you? pay no attention to what your friends say, but do get a totally unbiased opinion on your voice before you go public.
You have to make up your own mind.
But think about this - are you really going to let your friends make decisions about YOUR life for you or are you going to do what YOU want to do?
A real man makes his own decisions.
Real friends would support you. Okay - they might take the piss a bit, but that's just blokes for you.
