After a long gap, I am back to posting. I was actually busy with mid-terms, cross-grades, and some projects; plus job.
Though still in beta, google has updated the looks of sitemaps interface and added some new features. One neat feature is that you are given a check list while adding a new sitemap. This will help newbies solve many sitemap problems; remember my Domain and Sitemap trouble.
Google will also email some of those tricky webmasters/SEOs that use black-hat techniques, such as keyword stuffing, obscuring font colors, doorways pages, etc.
