Before the Internet became publically available I used to haunt BBS systems, use things like QWK mail and FidoNET to participate in what was basically an early form of Newsgroups. Then, during the early days of the Internet I used Gopher and similar tools to perform research and stay up to date on topics that interested me. Before any of that was available there were local user groups and local hobby groups. But there has always (in my lifetime) been a user community that was available if you just looked.
Blogs have replaced Newsgroups to a large degree. Let me clarify that before I get a slew of comments or email. I mean for my particular purpose which in this case is staying informed on a variety of subjects.
A good example, rather than haunt the Microsoft Web site looking for the download link to Office 2007 Beta 2 Technical Refresh, I just watched my aggregator, sure enough, within minutes of it being available someone had posted the link and I was off to the download races!
Another example, I was recently using the latest release of an Atlas component and experiencing trouble. Google shed no light, nor did Ask.com or Kodors or any of the other engines, but about 15 minutes of searching through my RSS feeds found no less than 7 posts on the same issue! 6 of which had the fix.
Blogs, tending to be more frequently updated with high signal to noise ratio content, than any other medium, are more and more often my first choice for finding technical answers.
Newsgroups are still better as an interactive medium, but I spend more time than I would rather wading through posts that consist solely of some self elected enforcer being critical of another because they did not ask their question in the right manner, or cross posted it to too many groups, or did not use the correct font and point size for a question about xyz technology!
Anyway, I love Blogs!
Cheers,
