The grand scheme is to give Wikia contributors more options for how we communicate with each other, and to make the communication tools that we have more accessible. Some kinds of conversations work better when they take place over a long period of time, so that everyone can participate even if they're not around at the same time. Other kinds of conversations work better when you've got a bunch of people in the same place at the same time.

As part of this larger communication project, we looked at how people are using the current tools that we've got on Wikia. For example, a lot of wikis that use our blog feature are using it to have forum-style conversations. We're going to create a forum feature over the next few months. When that's live, we may find that people have the forum-style conversations on the forum, and they start using blogs for something else... or they may stop using the blogs at all.

So it's possible that an old feature might become obsolete if it turns out that the new feature meets that need in a better way. It depends on how well we do our jobs creating the new features. :)
