Tech's role in Katrina deluge

's bloggers have posted comments from readers who want to pitch in tech skills and gear to help with the Katrina nightmare. Someone even suggested turning the Superdome into a massive Internet "cafe." The lack of electricity has created a communications meltdown, cell phones being useless without service or a way to charge. Community tech tools involved include the sobering Lost and Found section of New Orleans's Craigslist. Those who can are snapping digital pictures and posting them to photo-sharing Web sites such as Flickr. A Katrina wiki has sprung up, but so have scam donation Web sites.
