What's the most important sentence, something like "don't use arc 3.1, it has a bug, use this stable branch instead"? It's a wiki, please feel free to make changes to it. It might be easier to discuss this using actual changes.
Update: Ok, I've taken a stab at making the biggest gotcha more clear.
Then again, perhaps we should rethink if that page is the best option. I work for Google, but Google sites is a pretty insane beast a lot of the time. For example, there seems to be no way to change the title of the site as a whole; the directions at https://support.google.com/sites/answer/90453 are out-of-date.
Some of us started a site at http://arclanguage.github.io a while ago, and it's now the canonical reference for arc functions. Perhaps we should focus on that. But it's a little bit harder to make changes to; you have to git clone, install jekyll, make changes, commit, git push. On a wiki you can stay within your browser. Do people have preferences?
Either way, we should have one place, and we should decide what the first sentence (in bold) should be.
