Suppose that the algorithmic timeline is a user discovery disaster akin to Facebook's. How implausible would a migration to an open source Twitter clone truly be? The chronological timeline itself isn't that difficult to build so I could imagine some sort of protocol being written for a Twitter-like service and then a client - website, app, etc - built on top of it. Twitter is unique in its position in that it doesn't have any real direct competition and that could change if it starts stumbling.
