@mcpaccard I made BirdSite for cross-posting selected toots to Twitter.
It is on-demand (so you can select which toot you want to cross-post). And if the tweet is too long, it will generate a link to the toot.
Generalistic and moderated instance. All opinions are welcome, but hate speeches are prohibited. Users who don't respect rules will be silenced or suspended, depending on the violation severity.
