Added a simple keyword search (doesn't support boolean). This should aid also in helping developers quickly determine if their mashup is on the map. Try "food" or "bike" and press search button to test it out.
Added "newest mashups" quick links at top of page. Simply displays 5 most recently added mashups.
Created a GOOGLE GADGET to search the mashups. The search in the gadget is actually much better than the one on the page, as it lets you know when there's a more general search you could be doing (e.g. if you search for Food/Drink mashups in Los Angeles,CA, and don't find much, it'll suggest searching in California). I added this as I found myself naturally doing that when using MashPlanet. To add the gadget to your homepage, click the image below.
