Joeuser.com is unique in the sense that it is a blog community. We all have our own individual blogs that then make up a greater blog (so to speak).
During the political season, it was really a challenge to keep the overall community from becoming radicalized. Anyone who has ever run a community knows there are very specific dyanmics that tend to work towards making a community radicalized.
The primary dynamic is critical mass. Critical mass in this sense being where enough vocal supporters of a particular thing are able, by force of will, to drive off supporters of alterantives. On JoeUser.com during the political season there were various points where both liberals and conservatives came close to reaching critical mass. What we didn't want to have happen is where the site became so liberal or so conservative that their opponents would vacate the site in frustration.
In customization, it's letting a particular program take over. One of my favorite customization sites this Summer became radicalized over a particular customization program to the point that the program's fans essentially drove off supporters of other programs. At WinCustomize the Stardock-oriented apps have radicalized it to a degree so that users of competing technologies don't feel as welcome as they should (sometimes you can lose the battle).
Right now we have relative equialibrium. I have complaints from conservatives and liberals in my inbox about the site being too much against them. But radicalization also occurs on a personal level. I've watched many users become more radical in their political beliefs. Don't. Take a breath. Step back. Just because some loud mouth who opposes your political beliefs got you mad is no reason to assume that all your opponents are that way.
Not every liberal is Michael Moore and not every conservative is Ann Coulter. Most people are in between. It's just that the more active people get on-line in debating a particular issue, the more aggressive they tend to get. That's why I take regular breaks. You'll probably notice that I'll go a week sometimes without responding or posting on a particular topic. It's not that I'm sick of it but rather I'm pacing myself.
People who stay intense for months or years at a time burn out. They burn out on their own passions and frustrations. They usually end up flaming out. I've come close many times.
So if you're mad at your opponents and want to just flame them all or think that "the enemy" has taken over. Stop. Take a breath. And remember, it's about having fun. Write about what you want to write about. Don't let the "community" control you.
