When I go online, I mostly listen to music and look for work as an extra in short films. I'm not on forums as much now, as there is not much to do. And I think Facebook took over the online communities. Before social media existed, people used chatrooms, and then message boards introduced a wider appeal for discussions, but now with Facebook, people are on that more.
Personally, I'm not a massive lover of Facebook, Twitter and all that. Meetup is better, and I guess Facebook would be more productive if I actually met up with people from there. Most of the 'friends' I have on there are related to a zombie film, so I have yet to meet them. It's unlikely I will meet any or many of them either, because certain ones already were in the film in other parts of the UK.
