Now, it appears that Twitter has at last made use of the Canadian-born technology. Josh Davis pointed out this morning that Twitter's new email summary is a near-replica of Summify's popular email digests. He believes this is a case of Twitter finally using Summify's software.
Josh suggests that the Summify-powered Twitter email is "useful and may bring users back," noting that it "will solve several issues that Twitter has." It does indeed exude the clean simplicity that Twitter executes so well in its interface. Looks like Summify was a solid investment for the microblogging platform.
