Ask HN: What TLD do you use for your personal site and email?

I'm in the process of moving away from my gmail account and would like a personal domain for my email and website. I already own firstnamelastname.com, the problem is that my first and last name together are really long and I'd like something shorter, for email especially (i.e. [email protected]). I'm thinking of getting lastname.co since lastname.com is taken and the guy won't give it up (funny since lastname.com was registered in Colombia and I think he's Colombian). My last name is short so it looks nice. I could come up with some hacky domain names but I like the simplicity of lastname.co

In this day and age, is there any downside to owning a .co TLD (besides typos). I plan to use [email protected] for email and I'd like to make some aliases for different services ([email protected], [email protected]). I would host a small blog at the domain name, I don't really promote myself too much, and if you Google my name it would come up at the top any way.

What do you guys use?
