My friend Francesco recently rolled out URL123.com, a site that provides some killer URL manipulation features. In his own words, “[URL123] is like tinyurl on steroids...plus, it's in .NET! Link shortening, sharing, and management with some really cool features.“
As far as I'm concerned, URL123 is like nanotechnology. It's magic. You just plug in a long address like http://www.flexwiki.com/default.aspx/FlexWiki.VisitorInformation and out pops a shorter URL to the same Web page: http://url123.com/2rhvh.
Rob Chartier writes “Very clean interface with allot of features including the ability to track all of your URLs and it even allows for you to create your own sub domains. For example, hit http://robc.url123.com/myblog which of course I have pointing to my current blog. Since I can manage these links it’s a nice way to alias URL’s which change often and keep my top list of URL’s super handy (like those pesky MSDN url’s).”
