Does comment syndication bother you?
TallGuyShort: I think it's a very useful technology, and I don't think anything should be done to prevent people from doing it (edit: publishing that data needs to be done carefully to avoid plagiarism). The web is the web, and any available information is, in my opinion, up for grabs. Of course, there are exceptions, but I think if you post a comment on a publicly-viewable website, it's public domain.However, having said that, I know someone who keeps very close tabs on people using similar software - and the information he's found about them is actually disconcerting. What he does borders on harassment, I think.
