simple & useful

For last one month, i am thinking how to have a mail signature with my blog URL. The problem here is, I have more than one blog & member in alot of social websites.
Do i need to list all the sites in the signature or ?

Recently I found this site which is nothing but a collection of my profiles in the web..checkout that
http://profilefly.com/duraionly

So, from hereafter i will use only this link as my mail signature which leads to all my blogs & myspace link..

what do you say?
