It's important that Bluesky increase its character limit to 500 because they are not alone. Today there are so many twitter-like systems that are useful, people want to cross-post. If I'm writing something I plan to cross-post, and I pass the 300-char limit, but I'm not finished, what to do. These days generally I view 500 as the actual limit, which means when my cross-poster tries to publish to Bluesky it fails. We should be trying to coalesce on an idea of what a text document is in the mid-late 20s. I've put my proposal out.#
