Hrmm since this is a logo contest why dont we add a REAL LOGO as well instead of just the orb thingy.
amongst bm's logo, I like the 1st, and the last. I like the last one better, no background, minimalist, and has a proper logo lol.
Least I like are:
2nd - it looks okay if it is without the "OK" part
5th - fonts are too thin, background style which shines takes too much of the "attention" value away from the words
