Just to clarify (and moderators, correct me if this is wrong)...Other Jellies max out on contributing to your score at 100 points, be it through a combination of awarding a GA (5 points), a GQ (3 points), or following you (2 points). Thus, as @Hawaii_Jake points out, it prevents potential gaming of the site. Visiting Fluther consecutive days in a row increases the score by 1 point a day.
There is also something about GAs that stop accumulating points if members who have already maxed out on you give you a GA within the first five. Hopefully, a moderator can verify whether that this is myth or fact or clarify it.
What it does encourage Lurve is insightful questions and answers. Humor, when appropriate, helps as well. Understanding the actual question and empathy are also more likely to evoke recognition. Trust me that in saying there will come a point where the reward (Lurve points) won’t mean nearly as much as the recognition (GQ and GA tick marks).
P.S. Have you checked out the Fluther Awards? While they don’t add to the Lurve points, some are affiliated with several Fluther classic threads. They are truly worth reading.
