@Gargron it's a good platform; hope it succeeds!
Aside: it's tough to see all toots under the root/ main toot, some get buried if a reply is made to a reply on the main toot. Think its coz of the linear display of the main toot and direct replies. Could a solution be showing the number of replies to each toot? Because a non-linear display will be over-crowded.
Thanks in advance!
