I've updated the .NET Developers Blog today. For one, all time stamps are now based on Pacific Standard Time (Los Angeles, GMT-8). The time stamps do not reflect the time of when the author originally created the new post, but when it was indexed by my aggregator bot. This is more dependable than using the author's post date in the rss feed.
Secondly, I've added an OPML and an RSS feed to the blog. The RSS feed looks a little bit different from the one that .Text generates, but it should still abide to the RSS 2.0 specifications. Let me know if it doesn't work.
Happy blogging!
