[SimpleDomaining]

I am not a newbie, but i have never had blog or talk domains. so just wondering which one would you prefer to hand register, if available

keyword+blog.com
keyword+talk.com

keyword+talk
+ can be used for different type of sites (blog, forum)

keyword+blog
- can only be used for a blog site

I would choose keyword+talk.com, keyword+blog is been overused, a popword
