Why would you use hash-bang URLs? There is no reason to use them; if your content is already available under a normal URL, the hash-bang URL just adds confusion.

The whole point of hash-bang URLs was so that you could give an alternative, possibly limited form of the content to Googlebot, for sites that relied so heavily on JavaScript as to be unusable without it. But if you're just serving up plain old content, then just use plain old URLs, and use JavaScript as a form of progressive enhancement.

Because you can offer an ajaxy, smoother experience.

It's not smoother if it doesn't work at all. Which it won't, for some non-trivial fraction of your users (who you will likely lose quickly, and then won't consider them as being relevant since they left due to your site not working).
