I think one piece of the issue is that some of the pieces of plot information are not necessarily worthy of making a post, and/or most of them are hardly earth-shattering on their own. They need to be pieced together by the various characters who have been given them before they start to seem more mysterious or intriguing, and it doesn't make sense for each of our characters to post ICly about each individual bit of information.

As I said above, I'm BIG into having characters chat about these things ICly rather than having some OOC infodump somewhere. I think it might be interesting to have some mechanism within the game between the characters to encourage this sharing of information between themselves though. Like rather than just randomly posting a "study group", Wrathion (or someone else) were to establish themselves as the main InfoGatherer, or several characters are the InfoGatherers, and there is a structured meeting log as well as an open invitation to message fellow members of the Study Group for Theorizing, or SOMETHING LIKE THIS. Just to encourage more structured IC interaction about the plot, especially for those of us who are really looking to get out our red thread and go wild
