type in google "free blog" and the results are instant. Best is anything running wordpress. I suggest you invest a little and get your own domain. In the long run it will be worth it.
There are soooooooo many free blogging sites around. First off, you could try Googling "create a free blog" which is bound to give you hundreds of different options. Or, you could take advantage of one of the thousands of WordPress MU sites out there on the internet.
whosedomain, I know that you said that you wanted a "free" blog, but it is really probably in your best interest to pay a little bit of money to get a lot more benefit in the long run. If you consider that a domain name might cost around $10 USD for a year, and some cheap web hosting would cost around $5 USD per month, you could easily place a Wordpress blog on your OWN web server right now for just about $15 USD. By doing it this way instead of opting for the "free" option, you can always grow your site to fit your business, and you will be able to manage any subsequent sites that you create by using the same host for the same $5 USD per month! Good luck to you, whichever route you choose! C.A. ContentConcepts
