Something in the $4.99 a month range would be a no-brainer.
Going forward I'd see the most important features to add as:
* some simple text formatting: bold, italics, bullet points.
* clickable URLs (opening in a new tab)
* a way to cycle throw the Z-order of the stickies, I keep moving them around to uncover the ones underneath
* fixing the weird bug where by new stickies appear off screen sometimes (Chrome 12 on Windows 7)
* Iframe integration -- let me create a sticky that embeds an arbitrary iframe. This would open up a whole pile of possibilities.
* Integration with a mobile app that replaces the corkboard metaphor with a simple pile of notes.
