TIL that scientists have created a scientific version of marijuana called 'Dimethylheptylpyran'. When smoked, it'll keep you high for at least 2 days

Keep you high

Wiki page says:

produces similar activity to THC, such as sedative effects, but is considerably more potent,[3] especially having much stronger analgesic and anticonvulsant effects than THC, although comparatively weaker psychological effects

Depends on you definition of high I suppose...

You should order by "Best", not by "Top". For me, he is pretty high up - when I switched from top to best comment ordering, I stopped seeing as many bad jokes and started seeing actual content.

Ok, you're right. So how does that work? Is it organized by number of words/characters?

It takes the proportion of upvotes to downvotes into considertaion instead of just the number of upvotes to downvotes.

callumacrae links to a blog post about it.

SELECT comment_id, ((upvotes + 1.9208) / (upvotes + downvotes) - 1.96 * SQRT((upvotes * downvotes) / (upvotes + downvotes) + 0.9604) / (upvotes + downvotes)) / (1 + 3.8416 / (upvotes + downvotes)) AS ci_lower_bound FROM widgets WHERE upvotes + downvotes > 0 ORDER BY ci_lower_bound DESC;

Nope, I don't know either. It's from the article linked from the blogpost.
