This probably is not the right place to bring this up but I couldn't find a better one.
There is an inconsistency in the reporting of 'users online'. The screenshot below shows '373' in the dark green bar but '362' in the block at the lower right. Golden rule: either be consistent or show it just once. 😉
[UPDATE] I monitored this page for a while, with occasional refreshes. The two difference between the two numbers varies quite a bit.
Part of the inconsistency could be that each place is making a seperate call to get the user count and the timing is different. They should be have a caxhe so that all places use the same data and only one call is made at a time.
