Hi Paula,
I’m happy to see you back and read you again!
Well, FP3+ has been launched and some people are happy, but a lot come here to ask for help or complain, it seems the Update to Android 10 is full of bugs 
while the new camera modules are always a cool thing but not so much worth it, according a lot of people’s opinion, except for the front camera (Fairphone team is working on updating the camera software).
Regarding people, a lot of newcomers, but there is a new and very active forum moderator and Fairphone angel called @alex21, @BertG has also been promoted.
As for angels, we’ll move from Mailman to Discourse soon, the beta phase seems to be successful.
And for riddles, I don’t have many of them but found this searching the web: 100 Best Riddles (with Answers) - Highest Rated Riddles - Riddles.com.
Have fun 
EDIT: In the worst case, you’ll find them boring, which is good news
