Cool. Easy to use and post with.
I'd recommend customizable tags, we're so used to it it feels awkward without it. or even just as checkboxes to give us some options.
Add meme as a tag.

That's about all I can say about it. I liked it, was easy enough to use on the computer good work.

As future work, it would also be really cool to allow us to use this to post comments on posts or other people's comments. I think building this function would really open it up and make it much more versatile. (Also something that your competitor doesn't have and isn't interested in doing)
