nice
Awesome man!
Not to pick on #7 again, but imagine if you had to make an avatar out of that? Seriously... how would you do it? It would almost have to be the whole logo which would look very small all condensed into a tiny avatar for TechNibble, Facebook, Twitter etc. The one you chose is super simple. The head part works perfectly! Most people don't think of that with logos. They think which looks the "coolest", then when it comes time to use it things get difficult or expensive.
We recently changed ours also. We had one that I designed years ago that I liked for the most part. But the issue I ran into was that exact same thing. How could I use part of it for social media stuff or forums? The mouse part was a generic mouse, it wasn't 'our' mouse per se. Her is the logo on one of our service vehicles.
See how its an 'all or nothing' logo? The mouse is just generic. It has no seperate graphic to use as an accent or as an avatar like your nerd guy.
When we reworked ours this was one of the options. It was a triple thing of sorts. Had a CP in it for Computer Pro, was a face and also a mouse lol.
We didn't use that though and ended up with our current one. I was unsure at first but its working out. Not everyone see's it but its a 3-D CP which stands for of course 'Computer Pro'. It can be used separate as we do in the forum here. We are going to do our windows with it also. This isn't how it is now but was an option for a shop front redo.
And here is the the inside main bench sign redo:
Our newest service vehicle:
And lastly our business cards:
Sorry don't mean to bombard you with photos lol. Just want you do know that you made an EXCELLENT choice with your logo pick. I would have a 10' head painted on our shop wall lol. Also I'd blast that bad boy across the side of a van like this lol:

Your shop looks amazing. Makes mine look like child's play
