First of all: welcome. Now, as you all might know, this blog site, http://weblogs.asp.net, has a grouped RSS feed (a couple actually), which is called the 'main feed'. If you place your post in a category which is in the default list of this site, your post will automatically end up on the main feed. This is a nice feature, but as it is used now it kills the site.
At the moment, the feed is flooded with completely useless posts: posts which link to articles from 2 years ago, copied texts from manuals, very poor code copied from other websites etc. etc. More and more people are giving up on this main feed because of this. While what you post on your blog is your business, you have to realize that by placing the post on the main feed, you also affect others on this site. For example, I don't want people to unsubscribe from the main feed and I bet a lot of others here think the same.
So, dear new blogger at weblogs.asp.net, do yourself and us a big favor: write new content. We all know about a couple of search engines, and we all know how to lookup things in MSDN. We don't need random posts without any red line to point us to these articles. Instead, what we don't know (yet) is what your opinion is about topics related to .NET programming, what your experiences are with .NET programming, what your ideas are about how things could get better. Those articles are interesting to read and will attract new readers and existing subscribers to come back.
History learns that this flood of useless posts is temporary, but what's sad is that often people who unsubscribe to a feed don't come back.
