When ever I am looking for a .blogspot.com or a .wordpress.com the names I want are sometimes times taken. Then when I go to look at the blogs that have said domain name usually there is nothing there or last updated years ago. I wish they would expire these domains that are never used. It's frustrating having to come up with another name. Sorry for the rant. '
That is frustrating. The same thing applies to normal domains (i.e. not subdomains) too. Lots go undeveloped and the owners are unable to be contacted. I think it's best to just try to find some other alternative name available by using hyphens and whatnot.
Thing about domain names though is that sooner or later it will expire and you can snag it when it does Blog names NEVER expire and I know with wordpress once the name is taken it can never be used again even if the person decides to delete it.
Get a blog on wordpress with your own domain, its a better option ,,you have a lot of control about your blog and plugin
