Hi newbies! I'm following a lot of new people rn.
It's a bit laggy, spellcheck will mess you up a bit, changing words. But it's easy to edit.
Also, liking does nothing, you have to boost for others to see posts. Follow hashtags. Lots of great #scientists to follow here.
There is a bell next to people's names, I used it a lot at first to get notifications from people I liked for boosting. More cowbell!
Once you get going, they will show up in your feed and you can remove the bell.
