I can't resist providing my opinion on this topic so my answer follows:
First, FTFs are not officially recognized by GS and for good reason. They serve to cause discord. This game is meant to bring us to together in friendship and not cause strife or discord. Obsession of FTFs or any other statistic for that matter tends to force the game into a competitive mode and it was never intended to do that from the beginning and still is not if I understand the spirit of the game.
Second, getting mad or vilifying others about something like that takes all the fun out of the game. So what if you missed the FTF, there will always be others in the future.
Third, I use a GPSr and only have an older cell that does not have a WiFi connection when I'm in the field. Is it my fault that I have limited financial resources to purchase expensive smart phones or the cell plans needed to use the applications? No, it is not my fault and should not be held against me.
Currently, I am upgrading to a smartphone with a WiFi connection capability and, when that day happens, I will be sure to log the time and FTF right after I find it. I recognize that it is common courtesy, on an FTF, to log as soon as possible and not wait for days. Furthermore, if someone doesn't have a connection I would not expect them to stop what they are doing to get to a place that has a connection. That is ridiculous.
When a cache is published that is the time when the hunt begins for everyone regardless of FTF. The hunt is not over when the FTF is claimed. If you are 5 or even 30 minutes away and the FTF pops why would you turn around and go home? Just continue to look for the cache as the game was set up to do in the beginning.
