Obvious focus on both reviews and users for the YellowBot Home Page. Also, seems to use source IP to determine I'm in Denver CO.
13-ybot-2-results
Results page for YellowBot prominently features the tags and ratings. Uses Google Maps and promotes the use of a larger Map View.
14-ybot-3-tags
Following the FURNITURE tag from the results page illustrates some of the weakness in single word tag usage. Public Storage is a storage facility. It may be useful for 'furniture storage' but that's not what's implied by a search or refinement for 'furniture'.
15-ybot-6-map
Here's YellowBot's Large Map View using Google. Not a lot of additional information about the listings is provided in the side bar. Lack of a phone number at least makes this view a little unusable.
19-ybot-4-results
Lots of tags that are extracted from content outside of the traditional YP ad. Source of these additional tags looks like it's from some 3rd Party review site.
20-ybot-5-detailpage
Landing Pages for business listings on YellowBot brings together a number of user-generated content and 3rd Party content sources.
