Enforced immediate registration. Requiring a new user to register and provide a modicum of information is a reasonable request—I just think you should do it after you’ve sucked the person in. Most sites require that registration is the first step, and this puts a barrier in front of adoption. At the very least, companies could ask for name and email address but not require it until a later time.
A good example of a site that does the right thing is Netvibes. It allows you to do a high level of customization without registering. (Thanks to Glenn Kelman)
The long URL. When you want to send people an URL the site generates an URL that’s seventy characters long—or more! When you copy, paste, and email this URL, a line break is added, so people cannot click on it to go to the intended location.
Here’s an URL for a billiard table copied and pasted from the CostCo site. Just how many billiard-table models could CostCo be selling?
http://www.costco.com/Browse/Product.aspx?Prodid=11197553&search=billiard%20table&Sp=S&Mo=8&cm_re=1-_-Top_Left_Nav-_-Top_search&Nr=P_CatalogName:BC&Ns=P_Price|1||P_SignDesc1&N=0&whse=BC&Dx=mode+matchallpartial&Ntk=All&Dr=P_CatalogName:BC&Ne=4000000&D=billiard%20table&Ntt=billiard%20table&No=0&Ntx=mode+matchallpartial&Nty=1&topnav=&s=1
The justification often goes like this: “We create a long URL because people with Crays might break our code and see private pages. Seventy characters that can be twenty-six lower case letters, twenty-six upper case letters, or ten numbers ensures that no one can break our code since the possible combinations outnumber the quantity of atoms in the universe.” This is what keeps sites like TinyUrl and SnipURL in business.
Also, speaking of URLs, it’s good to have an easy naming convention for URLs. MySpace, for example, creates easy-to-remember URLs like http://www.myspace.com/guykawasaki.
Test: Can people communicate your site’s URLs to others over the phone?
Extra credit: People using Verizon and can do this despite its coverage.
Windows that don’t generate URLs. Have you ever wanted to point people to a page, but the page has no URL? You’ve got a window open that you want to tell someone about, but you’d have to write an essay to explain how to get that window open again. Did someone at the company decide that it didn’t want referrals, links, and additional traffic? This is the best argument I can think of for not using frames.
