I know the long seatpost is supposed to give you "suspension" or something but to me it just looks goofy. If I am making a high stack frame I would rather slope the TT to avoid lots of spacers and things up at the front.
Yes, "vertical compliance" of frames is far less important than you'd think from reading Bike Forums. Adequate comfort comes from choosing a saddle and a pair of tires that provide flexibility and having a bike with a reasonably longish wheelbase.
