I might be able to help out as well. I’ve certainly got some ideas 
I have 16 years of software and backend web development experience working on some of largest sites on the net (eBay and others).
Just add these to the template file front-page.php
<p><a class="rss-link" href="rss">All Recent Posts</a></p>
<p><a class="rss-link" href="rss/topics">All Recent Topics</a></p>
The reason why bbPress needs Oracle support is because if you are trying to integrate it into any existing site run by an actual company and not a hobbyist, there’s a good chance their user database is in Oracle (or MS SQL Server).
PHP supports Oracle so why should bbPress be tied to just MySQL. I don’t think it is really using much (if any) MySQL specific code.
This is one of the main selling points of PHPBB – it supports FireBird, MySQL, MS SQL Server, Oracle, PostgreSQL and SQLite.
I’ll echo some of the other comments and say that having a Codex for bbPress is key to it’s future. Shouldn’t this be something that is very easy for someone at Automattic to setup?
The other thing is better, easier integration with existing user database tables and site features for sign-in/out, registration, change password, etc. Most everyone using bbPress probably already has the rest of their site already setup.
You don’t users to have to have two logins, two registrations, two login pages, and two registration pages ,and two records in the database with the same info. This type of integration needs to be dead simple and straightforward in bbPress but it is not. If this was done properly, the most common site integration (bbPress with a WordPress blog) wouldn’t be the mess it is today.
Also, support for Oracle databases would go a long way to helping adoption.
I hear that. bbPress is missing a lot of the documentation and help that WordPress has. Fortunately, bbPress plugins really are a lot like WordPress plugins. They make use of actions and filters just like WordPress does. The assumption is that you’ll read all about WordPress plugins and then know how to write plugins for bbPress.
You can read all about WordPress plugins and actions and filters at codex.wordpress.org/plugins although this is the page you really want to go to:
https://codex.wordpress.org/Plugin_Resources
You can grep around in the bbPress files to see what actions and filters are available. If you don’t want that much work though go here:
http://www.mittineague.com/dev/bbpaf1_0.php
This site listing all of the bbPress functions is also invaluable:
http://phpxref.ftwr.co.uk/bbpress/nav.html?_functions/index.html
Do this:
<a href="<?php echo esc_attr( get_user_profile_link( get_post_author_id() ) ); ?>"><?php echo get_post_author(); ?></a>
There is also a patch here (see the attachements section of the ticket page below) –
https://trac.bbpress.org/ticket/1181
But I haven’t tried the patch myself.
To fix this you will need to remove the raquo characters from your core rss.php file. Then your RSS feeds will work again.
It looks like this bug was introduced in changeset 2323
