I haven't been blogging much lately because I'm hard at work on the new version of NotifyWire.  While working on a couple issues, I noticed a really interesting change in Craigslist's html. 

It looks like Craigslist is going to start giving image previews as part of their browsing experience.  This is totally speculation, but look at what they've included in the HTML in front of each item description:

<span class="ih" id="images:3mc3oe3pa5Pb5S65R79an8ac3b5bbcc6e1752.jpg">

Looking at the HTML above, you can see the "id" of the empty span is specifying the address of the first image for the ad.  Why are they doing it this way?  I'm guessing they plan to do image previews using jQuery, but we'll see.

BTW, the image for the ad above can be found at http://images.craigslist.org/3mc3oe3pa5Pb5S65R79an8ac3b5bbcc6e1752.jpg, so you can see how they'd use the information in the "id" attribute and jQuery to dynamically make the image URL.
