bzyr.com is of course 4 years old and is a 4 letter domain! however i haven't developed it while it was in my possession. the next one is new and might be trouble for copyright reasons i think BUT...I know it will get lots of organic traffic bc of an upcoming smartphone....motorolaetna.com i have a blog on it now so let me know about these two.
oh and bzyr.com is being appraised from urlappraisal.net for 8 grand? i think mostly because of the age?
