Even with counter arguments, the growth is impressive. I've been surprised that ff has not taken over Twitter. Two contributing features to any lack of momentum might have to do with the barrier to entry on ff being too complex and the design being too cold. - Andrew Baron from Bookmarklet

ha, I'm one of those at the very top of the chart - I just joined ff ;-) - Bob Walsh

What's complex? Comment - Like - Hide - they work intuitively. - Bruce Lewis
