Some curiosities/observations:

1. Is OSM now using the tile expiry code I implemented in osm2pgsql to 
work out what to re-render, or is it using something different?

2. I noticed the minutely deltas are now delayed by an hour (used to be 
about 5 minutes).  Is this down to server load?  If so, why are the 
servers suddenly so much busier than before the API change (there don't 
seem to be that many uploads happenning and I wouldn't have thought there 
would be a big increase in downloads since the API change).

3. The deltas are much smaller than they used to be and there are long 
periods where they are completely empty.  A look at the "recent changes" 
page seems to show that there really are long periods when no one is 
committing any data.  Is this down to people actually not trying to upload 
anything or is the API undergoing periods of breakage so that people can't 
upload anything?
