Ok, now you're getting somewhere with the last version.
Well I'm sure you can come up with some shape that relates to software or IT in general. Pac-man, mouse cursor, enter key, ones and zeros, etc.If you come up with suitable one while developing your idea why not give it a try?
I think there mild unease with visual whitespace inside the M shape not correlating nicely to the 2 whitespaces inside the "B". It's probably the shape because area ratios 1:2:4 should be about right. Well this is just aesthetics
Noticed you could build a lowercase m out of the B shape by turning it 90 degrees? Could you get something out of it?
