<blockqyote> Do you know if wordpress.org will be difficult to set up?
For those who have not blogged before blogging on Blogger is a learning curve. For those who are accustomed to push button blogging wordpress.com is a learning curve. For those who have not blogged on wordpress.com software and who have no experience in self hosting a site wordpress.org blogging is an even bigger learning curve.
Here all "geeky" stuff is done for us. When you self host a wordpress.org install you are on the front line. You hire a web host and aside from the hosting service you are the one who must be able to upload the software, set is up, perform all upgrades, install theme and plugins and update them regularly.
If they have never self hosted before, and if they are not experienced with using wordpress software, I strongly believe that many bloggers ought to spend more time learning how to blog right here before they self host.
