If you want your list to be included on `awesome`, try to only include actual awesome stuff in your list. After all, it's a curation, not a collection.
Research if the stuff you're including is actually awesome. Only put stuff on the list that you or another contributor can personally recommend. You should rather leave stuff out than include too much.
Have a succinct description at the top of your readme. Make sure your list covers a certain scope and nothing else. Link to other awesome lists if you think they already cover a certain subject well enough.
