There is no reason to share your life or give your time to something that is not interesting, and different things are interesting to different people. I find seahorses to be interesting fish -- the challenge of keeping them really doesn't interest me. If they were as easy to keep as a betta fish, I would still keep them. I really enjoy watching them buz around a tank, see how they curl and uncurl their tails to go up or down in the tank, get a kick out of their curiosity, like how they interact with each other -- even their "snick" is great. I think that the other people in my household were really surprised at how wrapped up they ended up being in the seahorses -- they are engaging creatures.
