If you get homesick, you can switch to the threaded mode. Go to the top of...this page, for example, and go all the way to the top right of the window where it says "Display". From there, you can pick a threaded view, or hybrid. If you want to subscribe to a thread, just click on "Thread Tools".

You can also search threads. On the bottom of each thread, we can all add "tags" for faster searching.

If you really get homesick, you can always go to the archives!
