Actually this is before I was born, and probably you, too (I don't remember your age), but remember how excited everyone was about the prospect of seeing the surface of Venus (because it's always covered by CO2 and sulfuric acid clouds with 90 times the atmospheric pressure of earth), and then when they finally got a lander to survive on the surface for long enough to send back a few pictures... and basically it looked like the Gobi desert minus the vegetation? Actually, Mars looks slightly more interesting.
Titan can only be worse, since its hundreds of millions of miles further away from the sun. It'll probably just look the same, but murkier, unless it really DOES have methane oceans. THAT would be WICKED-- but I still doubt that we'll see much because of the lack of natural lighting. But you'd at least think there would be weathering-- can't really say that about any other planet or satellite besides earth. Mars' atmosphere is so weak its done nothing much and Venus was simply unimpressive.
I was just kidding about the methane octopi-- I wasn't aware that any reputable exobiologists think Titan might have even single cell organisms, precisely because of what you said about the biological chemical reactions. There's just not enough sunlight to start any organic processes, plus its shown no evidence of volcanic activity (even if it once had, its small size would have prevented it from being active for very long, just like Mars. I don't remember off the top of my head, but I think Titan is MUCH further away from Saturn than Io is from Jupiter, so the gravitational pull shouldn't spawn volcanoes). This leaves lightning. I don't know enough about the creation of lightning to say that Titan shouldn't have it, especially considering Venus (not to mention earth) does have lightning. I guess if Titan has lightning there's the possiblity it could have life, but it'd have to be pretty sluggish life because the relatively weak greenhouse effect doesn't lift Titan's surface temperature above 100 K. But... I could be wrong!
It'll be interesting.
