Hi @crypto.piotr,
I am sorry for the late reply. I just learned of the memo you sent a while back. I like how communities look visually, and I like the ideas of organizing content in a way that focuses each user's experience based on their interests. I agree that the Hive-ID looks weird and non-descriptive, and that communities are open to the abuse steemit.com is. I do not know what can be done about that, all in all. I think any redesign of the layout to feature the content more promptly, and allow easier access to sub categories and subjects will enhance the experience of content creators and consumers.
