I've been here for quite some time, but I haven't really yet understood the following situation:

- A few weeks ago, I had ~2000 rep on SU, maybe a bit more
- When I then visited meta.SU, I received exactly the same rep without even posting or doing anything. Just the badges were missing (obviously).
- Now, I have ~2.740 rep on SU but only ~2.718 on meta.SU —
*Update:*oh, seconds after posting this, it got increased and is now the same. At least one question answered.

To my further confusion, here's the situation for SO:

- I have 1.430 rep on SO
- I have 101 rep on meta.SO

So, why is the situation different for SO?
