My RSS reader crapped out again, only reading a handful of blog feeds while failing to update on others. Somehow, the list of links to keep stretched to “Months” instead of days. So, I had like a bajillion records in memory.
I cut everything down to 7 or 14 days (depending on the type of feed). Now everything seems to be working.
This explains why I missed JayG’s link to a story that I credited to Say Uncle.
