Guy Kawasaki is at it again, with a new site called Alltop that, among other topics, provides a single-page, easily scanned aggregation of the main Macintosh news sites. After helping to create Truemors, a site that lets people post short 350-character comments about interesting things, Guy and his team discovered that a significant percentage of the Truemors traffic was coming from Popurls, a single-page aggregation site that brings together headlines from the RSS feeds of news and tech Web sites. That got them thinking about aggregation of other types of sites, and, with Guy involved, Macintosh news was of course among the topics they chose for their launch.

There's nothing particularly new about the concept of headline aggregation, but Alltop has a spare, elegant interface that shows the most recent five headlines from each site, displays a pop-up preview when you mouse over a headline, and lets you click through to read full articles. So hey, if you're not already using a Mac news aggregation site, check out the Mac-specific Alltop page, which will even alert you to the latest articles from TidBITS. And if you sneak over to another Alltop site to scan headlines about celebrities, fashion, sports, or science, we won't tell.
