For more elaborate roleplay, the forums are far more convenient, simply because you are less time-constrained and can add a great deal more detail. For example, small things like the tone in which a character speaks are hard to add in-game (imagine having to type *In a serious tone* / *In a mocking tone* or whatever for almost every line) but trivial to add on the forums.
Additionally, images can make a story more appealing to read (or look at, I suppose) for both the players involved and other readers.
To some extent, it's more "realistic" as well. A thousand years into the future, it seems incredibly old-fashioned to physically meet people on the other side of Sirius when you can send them a transmission over the Comm Channel instead.
