I’ve been among those from the beginning pointing out how useless Twitter was for search results at any level. It’s a great way to connect with readers, partners, customers and so on. But as a search engine, it’s not cutting it at all. And now it seems that the rest of the world is finally beginning to catch on with this idea.
Despite the benefits of trend spotting a Twitter search can provide, any results given by Twitter lose their value soon after the person sending the updates hits the enter key. So in response, Twitter is now only going back four days. I think this is a reasonable amount of history for Twitter to maintain. But hopefully, this change will also offer us less of the annoying fail-whale along the way as a result.
It’s also likely that the mindset behind limiting the database to four days stems from the fact that data changes, so there is not really such a need for data that may now be dated, by Twitter trending stats. Just one thought.
