For me it's trip planning, first, last and always.
I pretty much agree with everything saraf says, only I don't participate in any other forum.
I think the trip reports are the forum's most valuable, and possibly unique, resource. I have planned both longer and more frequent visits because of the "inspiration" of passionate and beautifully illustrated trip reports that provide a wealth of detailed information, and the enthusiasm of the reports' writers for their subject.
Almost equally valuable are the sections that provide information about and help with ID of birds, animals and plants. While much information is also available on specialist websites elsewhere, having excellent pix and detailed field notes of (almost) all the animals and birds (and even lots of trees and plants) that you're likely to encounter is a wonderful resource. One of the great values of this forum is that it's very much a "one-stop" destination, where you can find pretty much all the parks-related information you'll need and more!
Being able to ask questions of members who visit these parks often, and who not infrequently were there last week or last month, is an amazing resource. And the friendliness of members and their willingness to share information may be unique amongst such communities.
To me these are the important areas of the forum. I also think it's important to be able to discuss controvertial issues relating to conservation and to park management, but I am personally tired of beating the dead horse of speeding and rule breaking, since I've seen absolutely no evidence (except in KTP) of any positive steps being taken to combat these growing problems.
Personally, I have no interest in chit chat, polls, or the caption competions that took over the quizzes section for so long that I just stopped going there. There are plenty of social networking websites and it would appear that many members spend all their time in chit chat
I used to enjoy the webcam threads, and I still look at the actual cams if I'm on line, but I rarely look at that forum, because there are so few really interesting/unusual sighting posted; rather, there still seems to be a competion amongst regulars there to make the most posts, no matter how mundane. I also find the "insisted upon" format for posting webcam pix very difficult to page through, so I just skip it
Currently, I have serious issues with with new rules for posting pix in trip reports as I feel that the most valuable content on the forum is at risk of being seriously diminished and compromised. In my opinion, the trip reports are the forum's most valuable resource. While they may provide "entertainment" for members, their far greater value is the scope of information they provide to those who will read them six months, or even six years, from now. In my opinion, anything that lessens the depth and breadth of trip report content is a huge, inexcusable mistake. Thus, if these new rules stand, I will no longer be making the considerable effort required to contribute trip reports to this forum.
