[@JBRam2002], I actually argue for the dozen some-odd posts provided they still have useful content, are appropriate in forwarding the character or story's plot, and are of reasonable length. If they are rapid, short and to the point that they could make up one reasonably long post, that I would take more issue with; a collaborative project would work best there. The reason I say this in whole as I do is because activity on a topic is an enormous uphill battle. You not only need a proactive Game Master who keeps the plot moving and interacts with small details, in-character and out-of-character, but a cast of participants who are willing to be active and also [i]are[/i] active.

You are right about the scenarios when they should be employed; a scenario wherein no one else has reasonable ground for interruption, there's not much issue to be had. In an environment where there are multiple participants who are in some proximity, or have the likelihood of walking in on the conversation or event, that is where it should be avoided.

I have still yet to see them done well with any frequency.
