I've been steadily pushing updates to my blog. I threw it together in a few minutes when I switched hosts last year using ASP.NET 2.0 and the AJAX Extensions. I started rewriting the back-end last week in .NET 3.5 with a tiered design to make any new changes easier to manage.
Since I used .NET 3.5, I could take advantage of LINQ to SQL. I'll be the first to say that database design isn't my forte (far from it), and I cannot seem to get a handle on complex SQL queries. But LINQ to SQL makes querying exceptionally easy. Things that would take me two or more queries are now taking one. I'm learning alot about complex queries thanks to the ability to see the SQL query LINQ to SQL sends to the database.
I implemented a tag feature. The latest few blog posts have tags, and I plan on going through all the previous posts to add tags. I'm still on the fence of whether or not I want to add a comments feature; there are pros and cons to having one. But in time I'll make a final decision.
The next "feature" is the re-addition of the contact form. And this time, I'm going to take precautions to keep scorned spam victims away (hopefully).
[Edit]: Also, the RSS feed changed to http://www.wdonline.com/feeds/blog/rss/. The old address still works, and will work for a while, but go ahead and update your feed reader with the new URL.
