Thanks a lot for your comment @robcubbon. That is true. On thing that I have noticed a lot till now is the reputation.

Reputation increases with the reward people get. From 25 to 49, reputation increases at a rapid pace; often under 2 weeks and even in 2 to 3 days. But as the 50's approach, every next number becomes difficult to reach. I was at 49 in less than a week. The next dozen weeks have only taken me to 55. I was easily increasing one digit a week in July but since then it has been one hell of a task.

The initial speed means that the early weeks get more rewards and then the whole thing slows down. Rewards have dried down indeed.

Thanks for your feedback. I'll follow you to stay in touch.

indeed, I've noticed the same thing. I'm on 50 now and have been on 50 for a few weeks.

Happily, not anymore now. Congratulations for crossing the 50 barrier. I think 50 is some kind of a checkpost or something. It took me a lot of time too.
