Based on a tweet (yes again), I wanted to show you a good tip about HTML and internalization. This is also something useful for SEO, especially when you need/want internationalization for your content.
translate="no"
The main use case
The main use case I would know for this no translate HTML code would be for your brand name and your baseline. That way they will always stay as you created them.
Example:
<p><span translate="no">AC Consulting</span> is my brand name.</p>
Another use case
Another use case for me would be your name, especially where some people have a common first or last name. OR even when your name could mean something else in another language.
Another example:
<p><span translate="no">Arthur Camberlein</span> is my name and should not be translated.</p>
