Is there any attempt to debug the RSS feed? Do we know how often
it misses edits?

Great to hear that. I hope I can help.

OK, so maybe set it at 3 hours. But is there any timeout at all
today? I think many people can install tilesGen.pl and try it
out, without ever requesting a password for uploading. It is a
pity if this blocks anybody else from rendering the same tile.
Ever since I got involved in OSM, tile rendering has been a great
problem. Now with Tiles at home we have a method where more people
can help, and this is great. I think we need to look at the whole
chain of events from editing the map, to seeing the new tiles: How
often does the chain fail (e.g. RSS misses the edit) and when it
does succeed, how long does it take? If we can measure these
parameters, we can start to make improvements.
