I'm new to geocaching, obviously, if you've checked my finds. Hehe
I've been doing this from my smartphone because I already own that, & why pay another couple of hundred for a GPS unit when the phone can do that? Which, judging from a lot of the posts in this topic, is some sort of sin in the geocaching world.
I don't leave incredibly long logs because I want it to be new for the person coming along behind me. That's what I enjoy about the cache. I do leave more than TFTC because that does seem rude, and I compliment whatever I enjoyed about it.
I have a CO in my area who in every cache threatens to delete finds if it only states TFTC, (I saw this is now frowned upon) and it makes me less likely to want to do her caches because who does she think she is?
And... I don't know about the iPhone, but on my droid app, to post a log you have to choose found it, DNF, whatever... So there are no accidental logs.
All in all... It's a game people... Relax, and let people enjoy it. Isn't that why we do it?
