Well, I can't explain why I was getting 168xp yesterday while I only get 130 today. And I am dead serious.
Hell, Tenb can even check the daily event log and see what's wrong, if it exists.
The number is fairly random to begin with. The amount of posts you make in the day does have an affect so you may have posted a little less. There are also other things on the site that affect your exp like toplist spots if you do things in the galleries.
