But it is not very active, looking more like a bot account. And the logo is not the best one. Maybe it worth to revive the thing? See as an example of better official accounts - https://twitter.com/rustlang, https://twitter.com/elixirlang
With the recent modernization of the site looks, documentation (latest odoc theme), etc, it makes sense to care about Twitter as well. Plus put the link to it from https://ocaml.org
I think these kinds of things tend to be done much better at the grass-roots level than at an organizational level. I’d therefore suggest pooling a group of people who are interested in updating an unofficial twitter account (assuming such a group can be found), to which they all have access. This way, the task isn’t relegated to someone on a team where there’s already too much work to do.
