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. Put only stuff on the list you or another contributor can personally recommend and 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 good enough.
