I don't know, but we now have the largest, steadily-growing, dev team and we're building Big Things on our own stack.
We're starting to deliver. Should only speed up, from here. The others had a huge head start, is all.
We did have to pool our efforts, to compete, tho. Hard to compete as a Lone Wolf, anymore. Need to form teams.
