In the earlier Game of Go proposal, all computer Go questions were on topic, but I'm not sure if they are on BGSE, too.
Computer Go basically refers to two things:
Algorithms and knowledge related to writing computer Go software
Explicitly not using Go software. This includes for instance Monte Carlo, the SGF file format, a memory structure to store a goban state or using telnet to connect to IGS.
From my point of view, this case is clearly off topic and should be asked at, say, SO instead.
Practical use of computer Go programs and related research
Case 2 would be my main question. This consists of, for instance, playing games against GnuGo, using MoyoGoStudio for pattern search, android clients for Go servers, game theory.
