The primary issue has been the economy. People don't have the money to spend. We have seen in my community, the cancellation of popular annual events, that you would have never thought would have been impacted, in arguably one of the wealthiest communities in the country. These tough economic times are forcing everybody to re-evaluate the cost living, what is most important to them, and striking balance in what will undoubtly be a major change away from mass consumerism. Time has become precious again, our friends and family in the realm of real life have become important again. It's a shift in priorities on a large scale.
With that being said, this is why Twitter and Facebook have been growing expotentialy. They are the simplest ways to stay tied to your sphere. And, I believe these invaluable formats can only enhance forums such as this one. Plus, there is a huge movement of people, such as myself, who have simplified our online lives. I made the choice to stay here, on Facebook, and now Myspace just for music and costume buddies. I was on 17 plus forums over a period of 4 years, and alot of that added to pure duplicity. Today I am only on the 3 online "destinations" I just mentioned. I got my life back and it's has been great.
What's happening is, is that people are having to ween themselves from over 2 decades of credit induced decadance. Credit became a second source of income for a majority; and now people are forced to not only save, but cease the use of credit all together. That's why banks aren't lending too, they need you to save to bolster their balance sheets. It's a double wammy to the free market. It will take time for this recaliberation to cycle, and as a result forums of all types of interest will reflect this shift. CGClone hit it on the head too. We are just another real-time litmus test of the bigger overall picture.
And on another note, me personally, I am sick of Star Warsing (but I am still gonna make armored costumes and party at cons, time permitting) I have gotten rid of most of it in the last few months, only keeping my most prized possessions. I just finally "OH-DEED"
