Most glossaries are just terms and their definitions. Maybe I should call this a mini-encyclopedia since I'll be addressing not just terms but also topics, and I will provide not just definitions but explainations. Call them techie-columns, enhanced FAQs (frequently asked questions) or whatever you like. If I bring up a term, a situation, a technology somewhere in my columns, recommendations, etc. I will take that as an opportunity to spell out the details in this section of the site.
Look for: Ad-ware..., Hardware Abstraction Layer, caching...
