Thanks to quick fix by Sarah, the OSM updater is now working, and will
catch up shortly.  I am still looking for a permanent home for this
service, as I am pretty sure it would be highly useful especially for tag
analysis and data validation.

mmd, thanks!! I was asking earlier and was told that there is no way to do
complex comparisons between tags in different objects. I really hope we
could teach SPARQL to do all the amazing geometry work that Overpass can
do, but I suspect there are significant number of queries that are easier
to express in SPARQL.  If only we can join the two :)
