"People comment more if a painting and modelling project is put in the Forum section than the Blog Section"
it seems like having a forum post for tracking your painting and modelling is better than having a Blog in the blog section. Just scanning down the page there are a lot more comments on Posts.
Forum/Blog users don't seem to comment much on the blog section. You get quite a few likes or reactions, but very little critique or feedback from what I've experienced.
My answer to my own question would be that if you are working on a project don't put it in the blog section, put it here. Use the Blogs more like a diary to track your own projects, but don't expect as much interaction.
