The reason we went with only 5 tags can be found in the introductory post under the sub title Wait, I Only See 5 Tags?. As for the media part, uploading pictures and video and such, that would classify us as more of a front-end like Partiko or eSteem and we have not designed it to do that. Granted, you can make a full blown post if you wish, but you would need the URLs of the media you wish to share for your post. I hope this makes sense and hope you continue to use our product!
