Integration could be the hardest issue to commonly overcome since it can be argued that corporate culture must change to accommodate micro-blogging. An internet architecture called OStatus has been developed so that microblogging can occur seamlessly across multiple corporate platforms. This protocol has evolved into ActivityPub, on which the Mastodon federated platform has been based since version 1.6, and on which more and more platforms making up the Fediverse are based. Users of these platforms are member of a specific instance running one of the softwares of the Fediverse, which can interoperate as a federated social network, allowing users on different nodes to interact with each other. This is intended to give users the flexibility to select a server whose policies they prefer, but keep access to a larger social network.
