I made a very similar suggestion, perhaps less well articulated, just a few minutes ago on HN re: instragram v2 going to multi-DC;<p>When there is a write up of &quot;We just did this super awesome scaling migration to the new hotness!&quot; -- there will be mini-how-to articles in them... or at least more in-depth reasons why and for what problem they were specifically solving.<p>A how-to-wiki-gist? with &quot;this is how you connect X with Y over ABC service in order to eliminate problem XYZ&quot; would be great and allow for people to contribut to the how-to...<p>But we&#x27;ve been saying this for 15+ years... :-)
