Hi!
OpenStreetMap is a map that anyone can edit and anyone can freely reuse. It has a huge ecosystem, and can thus be a bit confusing to edit or to work with.
I thought that having a weekly thread to ask all beginner questions would be nice for everyone interested, so - go for it!
If you know the answer to a question, please answer (so that I don’t have to answer everything).
That doesn’t sound too old to me! The satellite images in my area are from 2020. There have been some infrastructure changes since then, but in general construction takes a while so a few months shouldn’t change much. If you’re working in an area you know, as another commenter mentioned, you’ll be fine working from this imagery.
Also, unless you know there is new imagery coming, I don’t see any point in waiting because for all you know none will come for a year or more!
