Social forums offer no practical value.
What I like about the WordPress community is that it is an ongoing dynamic relationship of people sharing a common goal. Those that put in the effort to run a blog have a certain quality that sets them apart from the run-of-the-mill personalities that fill social forums such as Facebook with the trivial and the brain-dead, which is food to WordPress blogs like Why Oh Why Facebook?
I bailed out of the last social forum that I still was a member of by deleting my account last week. Social forums, the sort like Facebook or online forums, means you have to mix with the trolls, the stupid, the haters, plus all the trouble they bring along. With places like WordPress.com, and to a certain extent Twitter, you can control all that nonsense. In social forums you do not have much creative control over your contributions, nor over your privacy. I still am unable to figure what people find is so appealing about Facebook.
I have run a recent trial on Twitter with another account, which proved useful on the networking front. I have noticed that some WordPress bloggers also use Twitter to good effect. I like to network with like-minded people so I figure Twitter will enhance that experience.
I like Twitter that it still supports personal privacy, and is especially protective of personal information against government attempts to gather information, and to censor information. I dislike the trivia along the lines of “I am having a pizza tonight” (yes, my life was enhanced by this useless knowledge of you having a pizza). Overall, networking wise Twitter may show potential.
