Reefing is perceived as a geeky, complicated, high knowledge hobby. Honestly, many of us are here _because_ it's perceived that way. If it weren't, I'd guess that many of us would have chosen another geeky, complicated, high knowledge hobby.
Does that 'hurt' the hobby? No... but it might keep the participation numbers lower than they would be were it perceived as simple. Are lower participation numbers bad for the hobby? Depends on your point of view. If you're selling reefing supplies, ok, sure. As a more typical hobiest? Eh. If everyone had one, I'm not so sure I'd _want_ one!
Look at other things you do for fun. Me? I'm a precision long distance shooter (another geeky, low participation hobby), and I'm into 3D modeling and printing (yeah, that too).
One question others here seem to be more interested in:
IS the hobby complicated?
Not necessarily. My old 240g DSB system was _far_ from complicated. High tech Gadgets? Where would I have gotten stuff like that in the 1990's? Plumbing from the hardware store, drilled myself, sump was a stock watering tank, Southdown play sand from Home Depot... Tank was very successful, though somewhat atypical of the times.
I remember when everyone was using Home Depot sand! LOL
