starting implementation using tailable cursors
provide a ref to the stream so we can destroy it when a client disconnects
dumb down the server a bit and make the client more intelligent about what tweets it's receiving and how to order/display those
it can get a little flashy, but this is a much better way to update the interface when the list changes
eventually, the entire list doesn't need to update each time
can safely delete this file now
TIL: Array.slice does *not* include the end element
update the threshold to the count of the lowest ranked tweet, not the one just added
add a limit to the tailable cursor so we don't replay the entire log
only consider tweets in the last 24 hours
only update the threshold if the list is full
store the threshold for the client on the server-side and don't send tweets that do not meet the threshold
only update the RT count if it's more than the previous, the stream with counts is not necessarily in ascending order
make recent tweet time limit configurable
