Only if you do it after running the A/C or live in a humid climate. And if the fan's off, it won't do diddly.

Your statement about saving gas is obviated by the fact that even when the temperature outside is 60 farenheit I must turn on my air conditioner to maintain a comfortable cabin temperature. These are times when I keep my windows closed due to traffic noise.

No it doesn't reflect poor design, practically every damn car known to man does this because the intake for every car is behind the hood. So whether you get heat from the engine compartment or off the hood, you're going to get heat. So you can get some foam or rubber weather stripping and seal off the back of the hood if it really bothers you that much (which I did on my old SRT-4 and it worked great since the turbo was below the HVAC intake, but you're negating a great way for your engine bay to dump heat).
Also, dropping your windows below 50 isn't that awful. Your grandparents did it for the first half of their lives at least.

This is a dumb statement. There are TONS of valid reasons to use recirculate, especially A/C efficiency and reducing vehicle exhaust going into your lungs (which is really, really bad for you over time and in traffic, and is responsible for an awful lot of lung cancer behind cigarettes).

With the system off, my car blows warm air like other have stated. It blows harder when at speed, less when sitting. This tells me it has to do with something being open to the atmosphere, as high speeds equals more warm air blowing.
I think part of my issue#1 has to do with the AC having to overcome the warm air that's always blowing into the car.
Switching the fan on, temp to LO, and pushing the recirculating button, and then switching the system off doesn't change this.

The A/C compressor is connected to your engine. Higher RPMs = colder air. Recirculating cold air is why we have central cooling in modern houses that doesn't cost an arm and a leg.
And doing it properly and switching off should fix it.
Seriously, I don't know how this many people are completely void of HVAC knowledge on cars. My CRX did it. My 626 did it. So did my SRT-4, 330Ci, and Outback. This isn't 400 level thermodynamics, it's common freaking sense. Unless you want to put an HVAC intake snorkel on your damn car, it's going to blow warm in the summer.
Man up.
