I prefear Wordpress (and if it's possible self-hosted). Wordpress it's more dynamic, it can accept plug-ins and more elavorated templates.
But in the other hand, Blogger it's owned by Google and this convert it very popular.
I use Leopard for the dialy routines (code web pages and desgin, listen music, write papers, etc.) and I use Windows Xp SP3 for gamming under Mac OS X boot camp.
Yes, sure Kaspersky is better than Nod32. And it's a very good suite that provides a good security, it doesn't use so many resources and very fast and reliable.
