One of the main problem i had with my wordpress blog’s url was that it was too much long.now the wordpress team themselves have brought a tool for that . I too have used that to good effect. now you can get tiny url for each of your pages and posts .Actually it is redirected to your original url.Most of you have heard of tinyurl.com.with which we even can get our url shortened with the words which we like.
check this out.
even though wp.me is not providing that it too is quiet useful.The best thing of these is that it is permanent and absolutely free.Then why are you thinking of buying those short domains .
go … make the most of that….
