Google has a new facility which will email you when it finds an
article meeting your search criteria. This might be useful for those
compiling references. I've had one one set for "PostgreSQL" for some
time. Most days I get perhaps two or three alerts. You can also set
them for once-a-day instead of as-it-happens.
