Twitter still bugs you to create an account to access their content. (Try to see someone&#x27;s list of followers when you&#x27;re not logged in, even when that information is public.) Compare with Wikimedia where you don&#x27;t even need an account to edit content.<p>Further Twitter is still promoting a model where to talk to people you have to create an account on a centralized platform first. (&quot;Want to get support from a company? Chat with them on Twitter. You need a Twitter account for that.&quot;) Compare with email where you can email from any provider to any provider.<p>Twitter might be more open than Facebook, but they&#x27;re certainly not the champions of openness.
