Bittorrent technology is covered under this, meaning that I allow people to discuss it as freely as they wish. I believe that there should be a place on the web for every type of discussion, from areas for bittorrent discussion to areas for hacking, etc. Yes, there would be some areas that are developed strictly to share how to commit crimes or th such, and so be it. You can't stop the spread of information, the best you can do is try to influence how people use the information they have.
In all seriousness, bittorrent technology is really no different than standard HTTP or FTP transfers. You exchange data with a central unit, and depending on the type of site you may be accessing, you share data between users. This forum operates much the same way any peer-to-peer system does. The reason people target bittorrent? It speeds up how fast information and data can flow, never before had information been so readily available. If you look back in time when books were first invented, it created mass chaos for governments and highly held officials. The people had the power, this was new to them. Bittorrent is no different, people who have power have good reason to fear it and use propaganda to convince people not to take part in using it.
In terms of allowing bittorrent sites to be advertised, I see no reason not to. If you allow Wikipedia, Google, even other forums, then bittorrent sites should be encouraged, not shunned.
