eviltammy | Questions for geeky friends

Or anyone else who'd care to answer.

At one of my former places of work, I still have friends. Well, actually, at all my former places of work, I still have friends, but this particular person I actually keep in touch with :) She doesn't get some aspects of computers and, while I can help somewhat, there's a lot that's hard for me to explain. Mostly because either a lack of technical knowledge or it's just something that I don't do, so I can't really explain it to her satisfaction.

None of these questions are really technical, but I'm looking for help here:

1. Explain gaming - MMPORGS(?) or whatever they are. How you do them, who does them, etc.

2. XBox - PS2's - how do they work?

3. LJ/MySpace/Blogger/Vox/other social networking - what's the difference?

4. Does anyone know of something that the library & all the branches can use to cut down on the amount of spam they receive. In chatting with a friend, I came up with either using something like mail2web.com to delete spam from the server before downloading mail or using something like Mailwasher Pro. Something with a one-time low price tag? Mailwasher sounds good to me, but I'm looking for other suggestions also - things that are very easy to set up.

5. Anything new and hot that I can tell her about? Or someplace that she can check to see what's new and hot?

Thanks! ::Puts out plates of nice naughty bickies and lots of drinks for respondents and readers::
