If you read Coding Horror or Joel On Software, you already know about In a nutshell, it's a place where you can ask coding questions and receive answers quickly. You can also participate by voting answers up/down and answering questions. works really well, the overall design is very simple, clean, and easy to use.

The emacs community there is pretty small, but questions do come up now and then. In general the answers are fairly good (I think mine are stupendous, feel free to look at them and vote them up).

Like any good (modern) web page, this one has plenty of RSS feeds. This is the feed I use to watch questions tagged emacs elisp emacs-lisp dot-emacs.

Emacs Tip #27: midnight-mode

I generally have a single emacs session that runs for a couple weeks, up to about 3 months (when work does it's quarterly preventative maintenance reboot), and because of this, I often have dozens of buffers open. Periodically I'd go through them and remove a bunch - mostly to free up memory.

Luckily, there's a mode that already does that for you, periodically flushing unused and old buffers:

(require 'midnight)
The following variables can be used to customize the behavior of the clean-buffer-list (which is run daily at midnight). It responds to settings of the following variables:
I love finding packages that implement functionality I hadn't realized I wanted. It is very relieving, like accidentally scratching an itch I didn't know was bothering me.

Edited to reflect proper require statement.
