Hmm, i was thinking if there's any way we can include voice clips, like those supported by edeo.com, audioblog.com and stuff.
and uh, if there's a more convenient image uploading process, say something that can directly download my flickr images from my own account.
and if only we can edit categories tagging of each post by simple clicking of boxes without going to the edit page, that'll be sweet!
I have many ideas, but these are just the current ones i can recall. thanks wordpress.com, you've been awesome!
