I only use 'lol' on the internet, and then only if I'm writing in English, rarely when I write in Dutch (it actually means 'fun' in Dutch, which is pretty much a coincidence!)... I would never use it in real life, cause that's just stupid. Can you imagine going to some comedy movie and instead of laughing everyone says just 'lol' all the time? That would be sick - don't think it will ever get that far anyway!

But for the internet? I don't mind the use of it... it's pretty much the same as using the smilies anyway. I mean - what really is the difference between writing 'lol' or 'hahaha'? They both have the same meaning and it hard to show 'real' emotions through the internet anyway.
