Yes, you might be right. In fact, it might be a good way for the site to provide both with a little bit less competition between tech and non-tech posts.

The tough part is getting tags right. I went the organic route, as I assumed that I would either overlook topics that might be needed, or create redundancies. My site is still too small to see if it works well. I'm not a big fan of the subreddit approach, as I think it divides submissions and attention to a large extent.
