Since we're all very internet-savvy people, I'm sure we've all seen our favorite sites take their turn for the worse. Nothing lasts forever, especially on such a rapidly changing medium such as the internet. But what are some patterns that you notice that lead to the downfall of once-good sites? Is it the creator, the users, the content, or just plain bad luck?
I never know for sure when a site begins losing quality, but I know that the point of no return is when the site produces content solely for the purpose of the site itself as opposed to its original focus. Like, for example, if I stopped posting comedic lists, fanfiction dissections, and pseudo-intellectual rants on Basement Trooper in favor of posting nothing but Basement Trooper-themed contests, invitations for my readers to make fanart, and all-about pandering to what I would then call my "Trooperettes" (fan nicknames=DEATH), that would be my blog's mark of doom. I once lamented about Encyclopedia Dramatica, saying that the offensive tone of the new articles is only done to fit in with the older articles, which had actually used that tone for a reason.
In other words, meta content should always be avoided. It's lame enough in small doses, but a constant barrage of it is outright unbearable and can bring about the demise of any website. I'm currently watching it happen to Regretsy, and it's just plain embarrassing.
What say you?
