You're probably already using quite a few like Flickr, YouTube, or any one of the hundreds of social networking sites like MySpace (I still don't understand how *that* one got so popular), but have you been to any of these lately?
If you've got an itch to travel soon and your dates are flexible, hit Farecast. This site "predicts" the best times to travel, giving you approximate prices for the days you want to travel as well as a graph to illustrate the dates around it and flights to choose from. Or head over to Kayak.com and buy your ticket. Kayak is another mash-up site that searches flights from 120+ Web sites. Based on my cross-checking, it's a great site *except* for their "flexible dates" option. Travelocity still kills them on that.
Too bad I didn't find Wishlistr for you in time for the holidays. Be wed no more to just the amazon wishlist. Wishlistr lets you select your items from all Web sites!
And if you've been trying to figure out where to go to build your Web site with little hassle, the Google Page Creator in the Google Apps for your Domain is ridiculously easy (preview the under construction Kellinahandbasket desperately trying to find a job) not to mention that Google Apps,
lets you offer private-labeled email [email@example.com], instant messaging and calendar accounts to all of your users, so they can share ideas and work more effectively. These services are all unified by the start page, a unique, dynamic page where your users can preview their inboxes and calendars, browse content and links that you choose, search the web, and further customize the page to their liking. You can also design and publish web pages for your domain.
It's all free* and everything is hosted by Google. No hardware or software required.
All free except for $10/year to register a domain if you don't already have one. The dynamic start page seems useful if you're a small business with employees, but I doubt any of you will be signing up for your @kellinahandbasket.com email accounts soon.
I'll leave you with those for now.
Otherwise there have been tons of photoshop tutorials creeping up since the new release of CS3. Web 2.0 and photoshop focus in 2007? This just might be Kellinahandbasket 2.0.
