1.) This is open beta, therefore people are going to spend more time doing other things than grouping because as of right now there's not much benefit.
2.) Gil sellers spam the shout channel around camps pretty often. Sometimes they don't, but usually they do. Thanks to SE for not putting in an easier way to blacklist Gheyfjaj Selrsfji you have to manually type that name in by hand just to have another show up next time you stop by a camp. So many make a practice out of filtering shouts altogether.
3.) The chat window gets cluttered easliy. Unless you actively filter out everything you don't wanna see (And I have a strong doubt anyone bothers with using the filters.) anything others say will usually get shoved off the screen and disappear.
4.) Some questions might have already been answered. No offense but I know alot of people who are too lazy to check the internet to get their answers (My roomie's one of them. Instead of looking something up he makes me drop what I'm doing to go see.) and end up bothering everyone else.
5.) In cases such as camps, you'll often have those who just idle or go AFK for extended periods of time.
6.) Remember, while open beta more people than closed beta, this doesn't represent the numbers we'll see come release. 22nd will see a large sum but come the 30th that population will double if not quadruple.
