25 Web Sites to Watch
What's tomorrow's YouTube? The Web's next breakout hit may be one of these innovative, useful, and fun new sites.
Think that all of the great Web sites have already been invented? Think again. The Internet is evolving in new and inventive ways thanks to mashups that pull data from all over the Web and to AJAX-based interfaces that give sites the same degree of interactivity and responsiveness that desktop apps possess.
To keep you ahead of the curve, we've rounded up 25 innovative Web sites and services that are well worth watching. Some of them help you design your own personalized Web site mashups; others enable you to create video mixes, build wikis, share personal obsessions, and more. But take note: A number of these sites are works in progress, and user-generated sites depend on developing a critical mass of content, which doesn't happen right away. With that in mind, check out the following dot-com destinations. One of them may become the next big Web hit.
btw, there I found quite easy description for Spock as Search Engine-
Spock
If you spend more time than you should googling folks, you need to check out Spock.com, a search engine designed to dig up information about people. Start by typing in a name, or a search term that describe a group of people--for example, Motown Singer, or Rastafarians. The site then searches through various social networking sites such as MySpace and Friendster, along with more-general Web sites, and reports on what it finds.
For many searches, you'll get multiple categories of links. For instance, type in Barack Obama, and you'll get groupings like 'Democrat', 'Senator', and '2008 Presidential Candidate'. Click any link, and you'll find pages related to both Obama and the larger category. There are also links to photographs, tags, Obama's Wikipedia entry, his Senate site, and so on.
Spock is currently in beta form (its public launch is scheduled for sometime before September), and at the moment you need an invitation to gain access to it, but with luck you can wangle one by filling out the form on the site.
Spock still has its logo with BETA mark, but it's opened to public. Anyone may join- here is how:
And you may want to study its features by starting with my profile on Spock :) thank you.
