[Personal] My blog categories

I am really hoping that Google would introduce categories into Blogger. I can't understand why they are holding back on this feature given their excellent "label" implementation in Gmail. In anticipation I have started tagging my recent posts with categories names enclosed with "[]". So far I have come out with the following:

• PDA/Cellphone
• Internet
• Technology
• Personal
• Moblog
• Laptop/PC
• Toy
• Automobile
• Weird
• Misc.

Any suggestions for better or more categories? Or should I just go with a less granular system such as "Gadget", "Personal", etc?

Who knows, maybe I will follow the suggestion by Oldcola. The problem with this approach is that each blog entry is restricted to only one category.
