My worry is mainly from a security standpoint. As the program becomes more popular, it's more likely to become a target. If a determined and skilled hacker were to gain access, either from an oversight in the site's security or gaining access to somebody's admin account, what could happen? SwiftKit's domain being redirected is a perfect example. Moving the update check to a weekly check rather than every time the program starts could minimize the number of people affected in that scenario, although I know you would probably rather have everybody's version up to date to reduce headaches. Do you have anything in place to ensure the program hasn't been tampered with when downloading an update?
