Lordy, yes.
Wolfspeak gets a lot of bad rap, here and in-game. Sometimes this is deserved, sometimes not; moot point.
Usually, even with vastly complicated posts, you can make enough sense to reply, hm?
It might not be as fun as RPing with someone who posts things that you can always understand, true. But enough meaning can be extracted to not make the 'story' (as said above) worthless.
What bothers me is the people who RP and post for 5-post duration. The no post-cut (Waiitng for a person to completely finish before posting your own reply) rule is a gem! But when you have been waiting for about 3 posts to start your own, it is SO EASY to become bored, and forget what they were saying in the first place.
As Vespian mentioned, if the story is not clear, or interesting, why bother telling it?
