First off, I definitely agree with everything @Redglare said! I think doing the daily posts has helped me maintain accountability too, because it’s an easy way to show that I’ve read that day and track what I’ve read (obviously, the summary post does that as well, but it feels less “visible” to others since it’s just editing a previous post vs. a brand new post).
I also just enjoy sharing things that are cute or that made me laugh or fun new words I learned or whatever I may or may not have been responsible for bringing the tanuki into the last thread so for me, it can be fun and motivating to share with the group via daily posts. I think it’s nice to be able to see what people are up to each day, and I think it adds to the team spirit feeling as well ^^ I know I’ve also gotten good ideas for additional things to read/check out from reading other people’s update posts in previous threads.
One thing I will say about my experience doing daily posts is that it can become a double-edged sword of sorts - doing daily posts does add more time to the overall process (especially if you’re me and you spend hours writing posts as a general rule), and that can make it feel a bit burdensome sometimes. I’m going to keep doing daily posts this challenge, because I do have fun sharing, but I’m going to try not to pressure myself to post super detailed updates all the time, if I’m tired and don’t feel like it - some people’s update posts are much more simple than mine have historically been, and that’s totally fine as well.
