Most blogging applications are proud of their cross browser/platform capabilities.
They rely on a web browser and little else - what you will need is a web server that supports the applications minimum requirements (usually PHP and MySQL).
I've played with quite a few blogging applications using Linux boxes, Macs and Windows computers abd they all coped fine with the actual blogging application through the browser.
Blogging is all well and good (if you like that sort of thing) but I have yet to understand why someone takes the time or has inclination to read about the day to day life of sombody else.
I just don't get it.
That's my rant done and dusted.
Web server specifications are the critical part of blogging - almost any web browser works fine with the mainstream blogging apps.
