He was really cool and helpful, and he's kind of right (although there are some exceptions); it can be pretty tough to get an answer to anything other than the vague and general around here. Fortunately I'm at a point where that stuff still helps me out.
Thats always going to be the way though i suspect. Circuitbending isn't an exact science and this isn't really a dedicated electronics forum, if it was it'd be a lot more useful technically but also a lot more boring.
Questions about specific machines are always going to be a bit of a shot in the dark depending on if anyone out there has ever actually bent that machine before. Combine that with the fact that on any forum or group, people will always tend to ask a question but not come back to post details about what they did with the answer or how they solved the problem, and inevitably you end up with a whole lot more questions than answers.
Personally i'd have thought that if nobody answers a question then maybe thats because nobody knows the answer, so you should probably just try your best to work something out yourself and maybe post your conclusions here if or when you come to any.
It does seem a little extreme to actually go to the extent of deleting your entire account rather than just not bothering to sign in anymore. Its a shame as he made some excellent contributions.
