For no good reason, I just went ahead and registered andrewhuey.net, so I now have andrewhuey.com, .org, and .net. And I also registered andyhuey.com, .org, and .net. Several of these domains were owned by a domain squatter at some point in the past. That’s why I first set up my blog at andrewhuey.org — it was the only variation on my name that nobody owned yet. Now, they’re all available. I guess whoever was squatting on them gave up.
I use 1&1, and they currently charge $8 for the first yesr, and $9/year after that. So I’m only spending about $50 per year on domains. Not bad, considering I can remember when it cost $100 a year to register a single domain.
