I`ve had that happen a few times as well, and I must say I did enjoy getting a response from the COs to my log entries. Much more so than I would a "like" button. If I can, I will try to make my entry more enjoyable to read than just posting "TFTC", and if something funny happened during the search or en route, I will try to give a summary of those events. Animal encounters, beautiful views or something completely different. After all, before going hunting I read logs to check if there is something special about the cache or the journey to it. So I will try to give readers of my log an impression of the overall experience I had. And I know it will generate more visits for the CO if you post a good, humourous log. Being a little creative goes a long way.
