Does anybody know a site where I could make one for free and easy? A site I could edit on with a mobile device?
You can use sites like Twitter, Tumblr and Posterous for your Micro Blogging needs. All sites support posting from your mobile phone.
I don't quite understand your question, Are you wanting to make your own Micro-Blogging site from scratch? If so, then what do you mean by where can you create one?
I want to "host" my very own micro-blogging without all the script stuff. Is there a website that will help me make it?
try status net, check out the following url link http://status.net/products its an open source platform, and they said it supports access via mobile...(but I haven't really tested it...)
