GitHub topics was introduced January 31st and allows a quick way for maintainers to tag their repository for others to find.

In the repository list the descriptions for an repository become much more important. As more projects add topics a small change can be made to stand out like prepending an emoji.

Any emoji's can be used along with arrows to bring attention to the applications.

Examples: 🎁📦🕶👓💎🎤✏🖊🖋✒🖌💼📁📂🗂

Hopefully this doesn't get abused, but for now it's a nice way to stand out a little more.
