Well if you're looking to simplify the posting process, there are a number of options. It depends on what you need this for: to make your posting easier, allow other people to post, etc.
For easy posting without having to visit your blog, you could try the Deepest Sender Firefox extension (if you have Firefox).
Or you could setup post-via-email in Options->Writing
Or you could install the TDO Mini-Forms plugin from thedeadone.net. That plugin allows you to put a configurable form on a "page" (as in, wordpress-style "Page") that allows anyone to write posts directly to your blog. You can set those posts to automatically publish, or go to draft status instead. If you just want it for yourself, then password protect the "page".
