Ditto on the digital and analog for sure.
And maybe programming, ASM, C, BASIC (but microcontrollers cover that) and you will get others that will want a group. Like microcontrollers PIC, ATMEL. Same problem
I think this forum is great (best I have found), I know there are times, I wish I could have left an analog question, but left it in microcontrollers, since I was reading it with a microcontoller, and a lot of the analog guys do not use microcontrollers and to not read that section.
