At this time, it appears that our previously used methods for embedding Twitter content no longer function.
While there is no confirmation that these issues are related, Twitter recently announced rate limits on Tweet consumption, which have impacted third-party services such as TweetDeck. Our working theory is that these rate limits are even impacting Twitter’s own internal products and services such as Twitter Publish.
At this time, there is no recommended alternative for embedding Twitter feeds in websites, and as Twitter’s reliability and service model continues to change wildly and without notice, blog owners should consider the risk of continuing to rely on this service for publishing information to stakeholders.
