I am trying to get the problem of multiple, repeating "links" posts resolved both through TypePad (my blog host) and Delicious (the engine behind the links). At the moment, I'm deleting the posts manually. Hopefully I can get this dealt with quickly.
In the meantime, I'm very sorry about your poor overwhelmed feed readers and email subscriptions.
UPDATE (Friday, 10:20am PST): Delicious is on the problem, and has been fantastic. Public thank you to Dave, former Delicious employee/coder (and Parenthacker, apparently!), who noticed this post and joined in to help.
