Not quite on-topic here but....
1. Anonymous posting has to stop, it really does. The recent spate of anon posts was cowardly and I'm now looking at posts like the one above and wondering if it is the same person. There are precious few forums on the net that allow completely anon posting, and I don't think it's asking a lot of a person to create an on-screen name and add themself to the site. It may also be useful - given that this forum will only get bigger - to have an 'activation by email' setting. Sure, that slows things down a tiny bit, but lets face it, WP is not life and death, it's only a few minutes, and it goes further to ID'ing people.
2. The posting of a home URL must be more heavily encouraged. If people want help, then they should be prepared for those that want to help to look at what needs doing. I've certainly seen pages where the faults are nothing to do with WP, but with the way it has been used. The argument of "I can't install WP so it doesn't exist" is a false one to me. People usually have something on their site.
3. The database should keep a record of the IP that a poster is coming from, and make this fact very clear. Banning someone is obviously not what is wanted, but just having that option available would possibly encourage more reasonable behaviour. Nick changing then becomes pointless really.
This area will grow, and as it does, then like any sort of expanding organisation it needs increasing levels of rules. These are there to benefit us, not hinder us.
Just my 2p :)
