Data:

Includes US stocks with market cap > 100 Million, and price above $3. It doesn't include penny stocks.
You can download data from here:

Implementation: I am using sets for 'x in s' comparison, sets time complexity for "x in s" is O(1) compare to list: O(n).

Limitations: It depends mainly on the defined parameters for current implementation: It completely ignores the heavily downvoted comments, and there can be a time when the most mentioned ticker is heavily downvoted, but you can change that in upvotes variable.
