WordPress.com users and bloggers can use smilies in articles but also in the comment section of a blog. I like that pretty much because it adds some emotions and fun to a discussion.
But I wish it would be possible that we bloggers could replace them with our own images. That would allow us to create own sets of smilies for our blogs. It wouldn´t be anything else than replacing the smilies with different images in the settings and that makes me wonder why we still don´t have this option. This would be a small but nice new feature and it would allow us to personalize our blogs even further.
