Yep, nothing is perfect. Readmore has several problems: You get 'spoiled' without warning if you select the node from Newest Nodes, it is slow and painful to reveal multiple spoilers in a thread full of them, some people have 'readmore' disabled, ...

Note that putting CODE tags inside of an HTML comment will cause the 'download code' link to appear automatically, so you don't *have to* put in your own link. But that solution for spoilers isn't perfect either.

I recently discussed this and realized that the black-on-black or white-on-white method doesn't work for everyone. So I think we should just support <spoiler> and </spoiler> that would just get replaced with the *viewer's* choice of spoiler method. In user settings you could pick between a few methods including at least HTML comments, 'readmore' tags, black-on-black, or act like readmore but provide a link to the node with ;spoil=1 or such added to the URL.
