Exactly! At least add some kind of tagline..something along the lines of "Search for developers etc". See the freelance boards (eLance / RaC) for more ideas.

Live search of what? I assumed Twitter because you have a prominent link to your Twitter profile.

And the searches I tried didn't get any results so a message saying "Searching..." and then "Nothing found..." would be good.

seems pretty self explanatory, just type in iphone like it says ;)

Working on that!
