After some previous questions about polite scraping('s), etc. I wrapped up work on a three site, 50 newest questions display grid. Would it be all right to ask for some peer review of it on Meta Stack Overflow?
I will admit to borrowing the tag style design, but other than that I think it's pretty original, albeit rather bare bones at the moment.
:hover expansion of the excerpt and tags.
I'm currently working with the API that's in beta mode.
You can view that page over here. API page is broken at the moment It's not fancy or even very functional, but it's a work in progress and way faster then scraping. Update: Well I had some spare time so I reformated it and styled it like the scrape. Scrape page is still up until they enable this beta API on the other sites (this one included).
Tags are now supported with highlighting. Just type into the tag bar and find interesting tags across all three sites.
