Definitely like these ideas! I am still new to the scene, and tho I have added several post, I am still unsure of exactly how it all works, but I am a self learner and sadly work has gotten in the way of a few days of learning. So far I love it here, it isn't the same ol' song and dance as with other social media platforms. Trolls are everywhere, sadly, so the block feature would be nice, but I think the first post feature would be amazing. Steemit is still young, so if we had a way to reach out to newcomers, it may keep them around and help it grow and become even more amazing.
