Wholeheartedly agree on the wolfspeak front; it does nothing but make things drawn out and confusing. Though I RP literately, I honestly prefer comparitively short and concise posts that get the point across to a three post long description of the moon reflecting off a character's ice blue orbs. Long posts are nice in paragraph style, but it shouldn't be the primary objective.
As for the realism thing... that's a bit tricky. I agree that it would be lovely if Rps were what they claimed to be in ads, with realistic actually meaning realistic, but because of the way people interpret the word in FH it just doesn't work out. I run an RP about street dogs in a post-apocalyptic city, complete with radiation, mad scientists, mutations, the odd love triangle... not what you'd call realistic in plot or content. However, character designs have to be at least semi-realistic (neon/unnatural colours are forbidden, manes are technically allowed even though I kind of hate them because they're just so widespread it's impractical to try avoiding them, but you can be reasonably creative with markings and patterns as long as you aren't checkerboard or something), and I advertised as semi for a while. The only problem was that I would get things like purple spots, white hair, and swirly markings, which apparently still qualify as semi.
Anyway, that's my overly-long explanation of why I personally advertise as realistic, even though we really aren't. Even advertising as realistic I still get the occasional bright red nose or 'abyss' black, and some of them actually get offended when I ask them to change it to fit the criteria. I'd love it if realism went deeper than 'no neon' and not every wolf had emo hair, but... I don't see it changing any time soon.
