I miss being able to catch up on all my discussion topics using almost nothing except the space bar.
Most web discussion boards are just GUI on top of a message store, and the reading/posting pieces of NNTP are a stable, standardized API for interacting with just such a message store. If every VBulletin instance also exposed an NNTP interface to its message content, I think it would be a huge step forward for discussion-board usability. (Well, once the NNTP-client world woke back up again. Are there even any actively-developed NNTP clients left that aren't focused on guzzling pirated media from the .binaries. groups?)
