I think that noobs (like myself) should be encouraged to avoid annoying the DevGods on GitHub with anything short of a fully-baked well-thought-out bug report, but message forums are a lower tier of seriousness, about on par with chat, where novices and noobs can help each-other.
Chat logs have a lower search result helpfulness value, so telling people to only ask noob questions in chat will result in more repetitive noob questions overall. I [still](http://forum.nim-lang.org/t/2675/2#16772) think this forum needs more features, especially for categorizing threads. The poster or a moderator would tag a thread as a "n00b question", and people who don't like those could filter them out from their default thread listing.
