* We said we'll start out with blogs, because that's where we miss such a feature dearly. In the long run, anything which contains plenty of text could be "metahinted".

* Very useful suggestion, thank you. It is implemented now: ESC should close the popup window.

* Few commenters have suggested that. Would you prefer to see the entry occupy the entire screen or fit in a text-area of some sorts?. Anyways, reworking the preview functionality is on our TODO list.

* We'd respectfully defer answering this question in ample details to an upcoming blog post. We appreciate your understanding in this matter. To give you a short answer, however: no, it's not Lucene.

Thank you for your comment!
