All types of organisations.
Twitter is a free social networking and micro-blogging service. It allows users to send “updates” (or ’tweets’: text-based posts, up to 140 characters long) to the Twitter website via short message service (e.g. on a mobile phone), instant messaging, from their computer at home or work, or through a third-party application.
Don’t forget to add “hash tags” (“#”) to your posts. You have to add them to the keywords, e.g. #OSH. This enables other users to search and filter based on those key terms, collaborate and share relevant information.
