Operating reference sites, I’ve seen the importance of these gaining. Not that they are any more valid. For instance, many things are revealed with close-up stills that can’t really be done in other formats. As many blogs are simply chats without any real insight into matters. Little research. The vast amount is topical.
Is everything turning social networking? Is it simply a way to ‘validate’ information that anyone can post on a website? Or more of a personal disconnect with whom someone can identify?
Which means a whole lot more monitoring over site content, which may not be practical for the bulk of sites out there. But then, I have a hard time envisioning Wikipedia posting vids.
Only some of the highest ranked seem to escape.
