IMHO, there is one decision to be made:
- this is allowed, applications/editors are free to not submit
duplicate nodes in succession.
- this is undesirable, applications/editors should be the ones that
filter this out. If the current potlatch didn't filter correctly we'll
have to fix potlatch. However, on first examination potlatch seems ok.
- This is undesirable, applications might not submit them, but if
they do the API code should filter it out anyway.
I'd vote for 3. But then I'm not intimate with the whole system, so
feel free to ignore me.
Number two has the disadvantage of slowly poisoning the database.
Number one has the disadvantage of allowing the database to grow
bigger than it needs to be.

Q: It doesn't work. A: Look buddy, doesn't work is an ambiguous statement.
Does it sit on the couch all day? Is it unemployed? Please be specific!
