Most strata's have one or two "stackers" who gather proxies from owners and vote for or against on particular issues. Sometimes they ram things through or just act to obstruct so take care. This can happen in large complexes that are new. One original (dev) owner may even control the votes. Get to know who is who and stay in contact and don't assume they will vote in your interests. Check and give your proxy to someone who seems to reflect your similar interest.
In older lots resident oldies can take over who have nothing better to do and can act to avoid spending $ or over do it and want to charge levies to gold plate the joint. They tend to try and make onerous rules about fines, parking, noise, common area use, balconies etc. Find someone to give proxy who wont misuse it too.
