If you land on a protected question and are not able to answer (because you don't have 10 reputation earned on the site) you find this notice where the answer box normally lives:
That's weird and a little hostile. The call to action assumes you are here because you're trying to solve a problem. But if you land on a protected question, the truth is you probably are here to read something cool that was linked to from somewhere else.
We already build the page differently based on whether you have enough site rep to answer, so there's no need for one-size-fits-all here. If you are new to the site, the person who protected a question and when they did it serves no purpose. Calling out new users for writing spam answers when we know the person reading is a new user seems rude too. So instead of reusing the same notification banner, we should customize it a bit:
We are no longer soliciting answers from new users on this question. Can you help us answer one of the following questions instead?
Then instead of linking to the tags and the "ask your own question", list a handful of unanswered, upvoted and related questions. Telling people to browse the tags is a bit unsatisfying since there's no reason to expect they were drawn by the particular tag set. And telling them to ask a question just after reading a possible (probable?) bikeshed question and answers is asking for trouble. But showing them some example questions that are not terrible and that they have a shot of answering first will direct potential good contributors in a healthy direction.
