AAVSO occupies an important niche in procuring well-sampled light curves for variable stars and transients. It is often the case for novae at least that there is a high demand for high cadence light curves, and a large collection of small telescopes is perfect for monitoring these transients. This is true for many other sources as well, and as new large-sky surveys like LSST come online there will be more and more demand for photometric follow-up and high cadence observations on all of the newly discovered sources, which can not be effectively filled by large observatories. This is already the case with currently operating facilities, there are too many interesting sources to look at for dedicated follow-up facilitiyes and programs to keep up with. Plus, there are some targets with interesting effects that occur on short timescales, and require dedicated monitoring at much higher cadence than what is available with large surveys. There is a lot of science that can be done with the kinds of light curves that AAVSO has been collecting, that really fills a role that no other facilities can.
My research has seen a lot of benefits from AAVSO, and I think that the work being done here is quite important. I'd like to be able to give something back for all for all of the great data being taken, and to help improve the scientific utility of AAVSO data in any way that I can. I'm also quite open to helping AAVSO in any way that I can, and this seems like the most impactful way that I can volunteer.
