Twitter Buys Summify
Twitter has acquired Summify, a social aggregation service that digests the links in one’s Twitter feed and puts them into a daily summary.
And what’s now:
disabled new account registrations.
removed the ability to make your summaries public (i.e. all summaries will be private)
removed profile pages and influence pages
removed the auto-publish feature
disabled user registration from the website, iPhone and Hootsuite apps.
