Windows Live Writer
There's some fantastic stuff there, but I've been astonished at how many tips include very complex HTML instructions for things like setting up tables, resizing pictures etc. etc.
I've got a slightly vested interest in the following, since, as you know, the Husband works for Microsoft (though in a completely different part of the business) but a year or so ago he introduced me to a small downloadable app called Windows Live Writer which has transformed my blogging experience.
Essentially, it's gives you a WYSIWYG interface for blogging, much like Word in Microsoft Office. So you can drag images and text round the page, line them up side by side, make them bigger and smaller, just with your mouse. To insert a link, you just right-click on the link text and post in the URL. It's all easy peasy lemon squeezy and doesn't require an ounce of HTML knowledge. (The only time I use HTML is to add polls and other widgets to my posts).
I use Windows Live Writer with Typepad but believe it's compatible with Blogger and Wordpress as well. Don't think it works for Macs though. It's also now just out of beta, and doesn't have any glitches that I've come across. It's also the most intuitive piece of software I've ever used (much better than the usual overcomplicated Microsoft offerings - and don't tell the Husband I said that.)
Here's what this post looked like in Live Writer, just before I hit 'Publish' . The toolbar is down the right hand side.
