I only use it every couple of weeks and it was working the last time I tried it. I don’t use it very often as it makes backfeed from Twitter using Brid.gy a bit harder/less intuitive unless you know how all the plumbing works. Usually I POSSE content from my site to Twitter rather than use PESOS like this method.

It looks like you might have to go to https://threadreaderapp.com/account/author to click the publish button to send it to your website now. They’ve made a few subtle changes since I wrote the original. Did it work for you?
