I first started this blog just to have a place where I could test Windows Live Writer. In particular, I wanted to test being able to post to multiple blogs from one interface. I started with a SharePoint blog and a WordPress blog.
After that proved successful, the blog languished until I started using it as a storage spot for presentations I made at MUGOO meetings. (The MUGOO website is actually a wiki, for those who are interested.)
Now, however, I plan to use the blog as a spot to collect notes on various and sundry items. I already do similar things with my wiki, so it will be interesting (to me) to see which one I prefer.
