I noticed some things:

#1. comments that are upvoted a bunch end up on the sidebar for people to see.

#2. siftbot's comments (responses to invocations) can be upvoted.

#3. combining 1 and 2 could lead to Siftbot having featured comments.


I have been upvoting every siftbot comment I come across.
It seems like a "terrible" idea to encourage others to do the same.
