As Beaverlicious suggested, WordPress is very popular and an ok choice.
I would also recommend Twitter Bootstrap.
The advantage of that framework is that you won't get a hundreds of hacking attempts a day and if you have to or want to switch to a different host down the road, you just copy all the files and folders in your FTP root dir and ... move on.
With WordPress, moving to a new host is possible but very time consuming.
Chiao for now,
