I am fully expecting abunickabhi to bump this thread in a couple years.
But, yes, great explanation. "Bumping" can also be referred to as necroposting. Bumping is fine if you have something of value to add to a specific topic and you don't want to create a new thread and lose all the context of an old conversation. That's a great use of bumping but you'll still get some stick ups who will take it upon themselves to do some backseat moderator duties.
An example of bad bumping would be replying to a cubing NR/CR/WR that was broken many times since it's posting and saying something that doesn't pertain to that specific record. Another example is replying to a post from years past that's just a clutter post.
I don't think bumping should be entirely discouraged, but do have some discretion.
