That and working on bridges. Some people suggest that bridges solve the problem of onboarding but the quality of the bridges has been abysmal last I checked, the only one that is somewhat maintained being the IRC bridge and even that having some problems (like showing users online even if they aren't)
The main guy working on bridges left during the funding crisis we had last year, unfortunately. Luckily we have new people joining in May to work as their day-job on it. The IRC bridge should never show users in a room who aren't currently joined online on IRC (other than when it's recovering from a crash).
