I really like both versions, logo included, they're beautiful. As for the latter it's a matter of personal tastes, of course and everyone has a clue. (If the picture in it were to change, I'd prefer the diode symbol, which to me symbolizes a typical semiconductor.)
However if this forum is about electrical engineering I find the lightning bolt logo quite appropriate, i.e. to both electrical and electronics worlds. But then the URL dosen't match. I see two options:
- change the site domain name
electronics.stackexchange.comto match electrical engineering – well, ok, forget about it... - set the title to «electrical and electronics engineering»
Just my 2¢.
