Well, it looks as if you have surpassed me in a shorter time! Of course, when I first arrived here, I spent some amount of time trying to figure out the whole capsule/assembly/publication/promotion thing, and I really was not very active at all until several months had passed.
After that, it took me until about the 1 year mark to reach 100 hubs. Lately, I've been pushing hard, trying a couple of 30-in-30 challenges, which has me just shy of 200 hubs just past my 2-year mark.
At my age, I don't have the energy for multi-tasking that I used to, so things move slower.
