If you are looking for an easy to use and great program to use with your weblog, try blogjet . It works with most blogging software and has made me much more efficient.
The software does a couple of things that I especially appreciate. First, you can drag and drop from a web page. So the internal links are maintained. That in itself is a huge timesaver. Pictures are also included with the drag and drop feature, although they do not normally work as well.
Also, it allows you to work in a WYSIWYG environment. If you need to tweak the htlm, you can in the code section. That makes life much easier for the newbie blogger.
The only real weakness I have found with the product is that with WordPress 1.5 I need to post it as a draft as the time feature has not worked correctly.
The program is available for free for 30 days, and then you can purchase it for 40 dollars.
