To use Blogger, all you need is a browser that Blogger supports. The standard version of Blogger works with most major browsers including Internet Explorer, Netscape, and Mozilla. Until recently, browser support for Blogger Pro was limited to Internet Explorer, which meant Blogger wasn't accessible from a Linux or other Unix-based box. However, Blogger support has been added to Mozilla Release Candidate 1.0 and up, which means you can now manage your Blogger account from Linux and other non-Windows environments.
You can work around the browser completely by using the Blogger API. Once you've created the initial account and blog, post and maintain it via XML-RPC, using one of the client-side tools describe in Chapter 2.
You don't need to have a web site or a preregistered domain name to create a Blogger blog. You can use Pyra's community blog server, BlogSpot, to host your blog pages. However, if you want to host your own pages, you'll need a web site that allows FTP posting of content. It doesn't matter whether it's a Unix or Windows server, but it must have FTP access.
Other than these two very minimal requirements, there are no technical restrictions to running a Blogger blog. If you meet the minimum requirements, you're ready to create your first Blogger blog.
