Years ago I wrote a series of in-depth "secret sauce" posts. Since then, I've written a number of niche how-to posts. However, I saved our followers from seeing these obscure posts in RSS and Twitter feeds.
These incognito how-to's are in our XML sitemap and I figured they'd be picked up by the search engines and help out random people. In fact, they are all indexed and collectively pull a fair amount of traffic. However, recent client-related SEO work brought it to my attention that not linking to your own stuff can appear sketchy to the search engines.
This evening I wrote a couple posts for the OpenUpstate crowd about hacking USB devices with PyUSB. I figured I'd better link to these posts. While I'm at it, here's a list of all the how-to pages.
