Another thing I find frustrating is I've recently been thinking about creating a couple new accounts within specific niches to try to bring more of the type of content I enjoy here. The problem I run into is waaaayyyy too many dead accounts. Say for example I wanted to make an account about motivation/self help/personal development.

Every single name is taken @personaldevelopment @getmotivated @motivation @inspiration, etc, etc, etc. Few if any of these accounts have any posts on them, some maybe initially did a post or two and never came back. So many of the good handles are taken by dead accounts or seem to have been reserved by the developers.
