As a blogger, the best tool I have found for creating blog posts is Windows Live Writer. You can download it right to your computer and use it just like your blogging service. When you're ready to publish, it will send your post directly to your blog. Need to edit the entry after you've posted? No problem. Do it right in Live Writer, and click publish again.
I have found that it is much easier to create a post for Blogger.com. The main problem I kept running into was inserting photos, only to have it mess up my line spacing. I was constantly having to manipulate code just to get my posts to look normal. Using Windows Live Writer takes away all of that trouble.
Another fun feature is you can add Plug-ins, one of which is the ability to insert a Flickr image from your photo albums. I also love that Live Writer will allow you to search for a previous post in order to link to it. And if you're a big fan of using the strike-through characters,
like this, Live Writer has those too. I can't complain one bit about this program. It has made blogging a breeze.
