Everything #OpenStreetMap related is welcome: software releases, showing of your work, questions about how to tag something, as long as it has to do with OpenStreetMap or OpenStreetMap-related software.

There are many communication channels about OSM, many organized around a certain country or region. Discover them on https://openstreetmap.community
https://mapcomplete.org is an easy-to-use website to view, edit and add points (such as shops, restaurants and others)
https://learnosm.org/en/ has a lot of information for beginners too.
I first learned of Street-Complete here and I really like it.
It's satisfying to walk around, complete little tasks, and get prizes, scratching a similar itch to Pokemon Go.
Stuck waiting for someone? Add opening hours for a few local businesses.
Have a long walk ahead of you? See if you can add/check house addresses as fast as you can walk.
Want to walk off a few beers before heading home? Complete some tasks in the bar street.
Its a very constructive way to "be right" on the internet.
When it feels too much, I go back to the building where I live, and set small but realistic goals. Like, I want this block to be complete with all the questions. Then I look around and add things that aren't in the map yet, until my block is as close to complete as I can get it. An island of perfect mapping surrounded by more incomplete mapping. Only then I move on to another well defined area, preferably close to home. Maybe other people will see this example of good mapping and think "I could do that with my local area too!" My personal opinion is that OSM needs many local experts, rather than a few overwhelmed people trying to do it all for everyone else. I have my eyes on where I live, and notice changes over time.
