I plotted the data from the last two months and found a linear trendline. With May 26 being '0' and counting the days thereafter,
y = -10.866x + 2873.3
where x = # of days after May 26 and y = number of posts needed to hit 30k.
Therefore, setting y = 0 results in:
x = 264.4
Frink will hit 30,000 posts on February 14, 2014.
