A better male to female ratio. The only way I can think of doing that is if more women drag their male friends and spouses along, and for teachers to actively encourage their ladies to do so.
Also for people in general to behave less like morons to people who DO like dancing . I can see why some men actually hide their Salsa addiction and why many need to develop tough skins as well as their lead. 
Evolution. Salsa needs to adapt and evolve, or it will like other pastimes die off. Had my first taste of Zouk a few days ago - its a prime example of dance mutation afaics. Interesting space to watch.
A greater emphasis on practical dancing and .... above all else: craic. Had a class recently with a NI instructor - move was very basic, very basic but the instruction was so playful and the emphasis was so directed, not on the perfection of the move, but on having fun with your partner - as Salsa sometimes seems to be directed as about the search for perfection, the perfect lead, the perfect frame, the perfect (whatever ), and I forget that that road is a far too lonely one, fun is the reason I'm still with this hobby, once it no longer becomes fun - I'm gone
Good if the fun factor was focused on a little more in general perhaps 
More of a social scene - e.g. yes, everyone meets for Salsa , but do they meet any other times as a larger group e.g. for a few beers or what not? The club I'm currently with sometimes decides to go out as a group to a pub just for fun not for dance - the craic can be mighty, but afaik thats rare enough?
More people on this site, giving opinions and getting involved in chatting, instead of just reading . I know a good number of people read this site - why not post and give a greater depth to the site + a balanced view of the salsa world?? Whats the worst than can happen?
