Let's see, how about a list?
- It's gotten sort of boring. The same old arguments on the same old threads by the same people.
- Contrary to number one, the newbies don't help at all. They're typically just a recycled version of the last newbie to come in guns blazing.
- It's really not the place to "get smarter" as the stated intent of the site proclaims. Most of the articles on the front page are garbage. I think if one were to take the top ten writers from the site you would lose 90% of the quality there.
- Culture11 is better. More original content. You actually do get smarter there.
- Blogging is better. There are more options (like videos) and more freedom in general.
- The site has gotten slow.
- And buggy.
- The new comment editor sucks.
- The fact that the article editor doesn't even have really any editor features at all is even more sucky.
I'll append the list as I think of more stuff to add...
