I'm still amazed how many people think it's a great idea to have their resume on their personal website, along with their date of birth, address and believe it or not I've actually seen people put their SSN on their resumes.
Anyone who is familiar with bitter cynical social commentator Charlie Brooker might of already seen this:
"HarperCollins just asked to use one of my msgs in a book called 'Twitter Wit'. They can use this one for free: "HarperCollins R cunts LOL"."
The only problem there is with this idea is that when people feel passionate about a company or community that they belong to, they start to drink the kool aid.
Have you ever read the tech support forum for any games publisher/producer? I'll use World of Warcraft as an example:
Whenever a patch has been posted thats introduced problems, until its officially recognized, people posting about the problem will get a slew of replies that are along the lines of 'Its fine for me, therefore it must be your computer' and refuse to acknowledge that there might be any kind of actual problem with the patch.
My local computer parts supplier has a customer forum and I've run into similar things there, they were selling systems that were very well specced except for the PSUs which were woefully inadequate for any modern video card (They supplied 300w PSUs with their otherwise cutting edge systems) and when someone pointed out it was a shame there wasn't a option to customize what PSU was provided, rather than people agreeing, instead they got several hostile replies on how any idiot could replace a power supply and what did they expect for the price etc and generally praising the company while berating the poster.
It's fantastic people want to be involved and even volunteer their time but it does seem to ultimately lead to bit of a echo chamber and cheer leading.
