@kathhayhoe it seems this is happening to a number of high profile accounts and is not limited to climate science. A cartoonist I follow on twitter (who is sadly not on mastodon) mentioned a decrease in interactions that he is seeing. He thought it might be b/c of a change in algorithms. But it could be twitter flight IMO. doesn't necessarily mean people closing accounts though. Many (myself included) are just spending much less time on twitter than they used to.
