I've noticed that the "Best Posts" feature doesn't appear to be working correctly. For example this is what it shows right now: But yet this post has >40 Informative votes today and isn't in the list. So what other posts are getting rated highly that I'm not seeing highlighted by this feature?
That feature has some other issues that won't be fixed until some other major upgrades are completed. As to the particular post you mention, that thread is entirely excluded from the feature because otherwise nearly every posts listed in all categories would be from that single thread.
I like checking form time to time the "best posts" function of this forum, and it is apparently not working properly. For example the "most informative" only shows 9 out of 60 for the past week and zero for the last 30 days. Also the large investor's roundtable thread (the current one) seems to be excluded entirely.
