It's less intuitive than I expected. Adding a new tab is possible, but there's no button for it on the page (that I found). It does have pre-loaded links to things like Google Maps, Yahoo, Wikipedia, and YouTube. And, for some reason, when I type this in Safari (although I can't add a link), it tells me when I spell something wrong instead of me having to remember to check. (I usually only remember when I use the word "broccoli" in a post, because I know I can't spell it. In fact, I spelled it wrong explaining that - but it was easy to fix.)
What’s my motivation?
