Aw, did you make them just for me? How sweet of you! =P
Somehow, I didn't notice this change until I looked into my profile to change something. Interesting change, although quite useless. I'm not complaining though, lol.
Statistically, I post 400 times each month on average. So it would take a year and half a month to reach 5,000 posts, and 2 years and one month to reach 10,000 posts. Are you sure that anyone will reach that? Even I doubt that I'm going to be able to hit that amount before I leave.
From my standpoint, it'll take 7.5 more months to hit 5000, and 20 months to hit 10K.
