One outcome of no longer allowing unlimited public access to tweets is that it will become very difficult to cache or archive them. (And Twitter won't want to allow caches or archives since if course they could be used to get around read rate limits) To the extent that tweets (does Twitter not call them that anymore?) are an important part of the public record, including being able to verify whether someone really did tweet a certain thing at a certain time, this is a little bit scary. And just generally for our ability to preserve historical record, already threatened by the digital world, and apparently getting worse instead of better.
