Typically I'm sitting around with a notepad and pencil writing down and sketching out ideas. I can't spitball ideas with any of my friends or coworkers. I'm going to try collaborating and get some feedback here. This is just to get some creative juices flowing not for a particular project I'm working on. With all of you using Facebook and most likely twitter, what sort of Web based applications or "social networking" sites such as Twitter/Facebook do you think could be next, possibly you've had some ideas and think if they were created they would be embraced such as the above mentioned sites and really take off. I'm not running around like everyone else asking "how can I make a clone of these popular sites", instead I'm building off the ideas, technologies and general social acceptance to help get some ideas (as well as the pencil) moving on some things I might want to do in the future.
