* The all-versions page has a docs column with html/pdf links, and also
two links in the nightly builds footer.
* Specific version download pages have a link to the docs for that
version. (Only html, to save space.)
The examples make up the majority of the front page, and it turns out
that google used some of these links in "sitelinks" in search result.
These links should be the main entry points, and we ended up having such
gems as "Printf" be there. They provide a way to "demote" URLS so they
won't show there, but doing that for one link means that another will
pop in (and there's a limit of a 100 such demotions). So add this in an
attempt to make it not consider them as things that can be used in the
sitelinks. This might be reverted if it doesn't help.
(Note that this is discouraged as a way to "sculpt pagerank", but the
purpose here is not to affect how they crawl the web pages and make page
reputation flow, but only to cover up for a missing feature that ends up
with horrible sitelinks. The pages are scanned anyway from the doc
pages.)
* The main page's title appears in search results, so use "The Racket
Language" instead of "Racket". Additional minor tweaks to a few more
titles to make them presentable as search results.
* Add a `#:description' keyword to make it easy to add it to pages. Add
such texts to the main page, downloads, community, learning, people,
and mailing list pages.
* Add a <meta name="robots" content="NOODP" /> to the front page, to
avoid getting the ODP (dmoz) blurb, hopefully the new and improved
description(s) will be used instead. (If not, this should be
reverted.)
* Add a reference from the community page to the bug reports page.
* Make it possible to subscribe to lists right from the community page.
Improve the email input boxes with placeholder text and a short
explanation on hovering.
(Otherwise having both installed can be confusing since the uninstaller
has the same name; also, it's good to make a reminder for people who
want the other one.)
Also, just use the platform string in the registry key uniformly.
Also add a comment about detecting Win64 if it's desirable in the
future.
Indexing index pages is harmless, and also "nofollow" is appropriate for
public lists with lots of junk, advertising etc. We have nearly zero
spam, so following links in posts is fine.
