Medworm- another R.S.S medical engine

I wrote to you last week about medical R.S.S aggregator.
Today, for accomplish the subject I must mention Medworm.
Medworm is an excellent medical R.S.S engine.
It's claim to cover more than 4,000 medical sources. Including journals, blogs, organizations etc.
I don't have to rewrite the benefits of such web 2.0 tool for us.
Some of you already knows about it. For others is my gift for this weekend.
