Do not fuss over finding the perfect blogger web address. Chances are, it is taken.
Get over it and start blogging.
You can still title your blog whatever you want. Your name and your blogger url don't have to match.
When I renamed this blog, I discovered that toocleverbyhalf.blogspot.com was taken. Same for 2cleverbyhalf, cleverbyhalf, tooclever, and 2clever.
To add insult to injury, most of those blogs were blank--or nonexistent!
I just kept going until I found something free. Total time elapsed: five minutes.
