Ew Chrome. Ewwww. No, I actually used it for a little while, but like... I stopped. Too addicted to Firefox.
A talking sword? Now, I know zip-zero about Sonic and this Black Knight thing, but I guess it depends on how far this sword goes... If it tell you who's behind you, I won't approve. If it just annoys you mentally, I approve -- I mean. I guess you can, but I would like to know who can hear it. Even so, if you add any other magical abilities to it, I may deny it. Just a heads up.
