Over the past couple of weeks I’ve noticed an increasing number of people on Twitter saying that Twitter has gotten lame, gone mainstream, or that it has “jumped the shark”. There was a dramatic rise in these type of posts last week with Ashton Kutcher/CNN’s race to 1 million followers, and also with Oprah beginning to actively use the service. Honestly, I have been a little confused by all these tweets. To me, the beauty of Twitter is that you don’t have to read things written by or about people you have no interest in. As of now you have complete control over what shows up in your feed. If you don’t care what the Big O had for breakfast, don’t follow her. If reading about what Kelso did over the weekend bores you, don’t follow him. That’s the beauty of the service. Each user can essentially customize it to be whatever they want it to be. If you are one of these people that want to know every detail of celebrities’ lives, you can find out probably as much as you want. If you just want to talk to people you know in real life, you can do that too. You can see as much or as little as you want. If you are seeing too much info about stuff you don’t care about, it doesn’t mean that Twitter has suddenly become lame, it probably means you suck at choosing who to follow. That is not Twitter’s fault.
So, following this logic, if I see people in my feed talking about Twitter being too mainstream, be warned you will probably be unfollowed.
Stuff About Things 
I agree completely. As with most anything, you get out of it what you put into it. While it will suck a bit in terms of ‘mom and dad’ finding twitter…its good for the technology.
I think “jumping the shark” is all relative. It’s mostly ones personal opinion. I think Facebook has pretty much jumped the shark, what with all the (unneeded IMO) changes to the layout and now with PARENTS (oh, the horror) joining. But somebody just finding out about it probably thinks it’s great. Twitter will not jump the shark for me until I start having to read ads in the middle of tweets, or some kind of other crazy changes are made.
