We're testing out a modification to reactions (formally known as Kudo) here on the preview site at the moment.
It doesn't really make any sense to be able to react to your own posts, and some of you experienced different behaviour when you tried to.
To that end, we've modified the behaviour so that the option to react to your own post is now removed, but you'll still see the reactions that others have given you. Likewise, any post that is not yours, you can continue to react to as normal.
Feel free to check it out, and please do let us know what you think of this change! 🙂
Over and out, for now..
