Not for the first time, alternative models to page views are in the news.
This time, comScore has announced a new "visits"metric. "AJAX" is cited as one of the motivations.
comScore Media Metrix today released its monthly analysis of U.S. consumer activity at top online properties and categories for February 2007 and introduced a new suite of metrics based on site visits. The visits metric, defined as the number of times a unique person accesses content within a Web entity with breaks between access of at least 30 minutes, is a way of measuring the frequency with which a person views content, thereby illustrating a key component of user engagement. Included among the new suite of metrics are: total visits, average minutes per visit, average visits per visitor, and average visits per usage day.
As technologies like AJAX change the Internet landscape, certain measures of engagement, such as page views, are diminishing in significance for many Web properties, said Jack Flanagan, executive vice president of comScore Media Metrix. The introduction of these new metrics based on visits provides an alternative for measuring user engagement that tells us how frequently visitors are actually returning to the site to view more content.
Marc B. Stroz pointed us to a new Joomla module called TARR (Tabbed Ajax RSS Reader). TARR is using the EXT JS libraries, JQuery and the simplepie xml parser to display different feeds in a tabbed format. It allows for server defined defaults / favorites and for users to add to their favorites for later visits.

What is XSTM?
XSTM is a n open sourcelibrary which enables high performance object replication between processes. It is an object oriented Distributed Shared Memory, or a Distributed Object Cache.
XSTMhas similarities with technologies like Adobe Flex Data Services , JBoss Cache, Terracotta, Tangosol Coherence , ScaleOut , or IBM's ObjectGrid .
Our model is based on object shares, which work like file shares. When an object is added to a share, it appears on the other machines which have the same share opened. Modifications done to the fields of the object are from this point replicated between machines.
Read more in the project overview.
XSTMis made of three projects. The Java implementation is called JSTMand is the base from which
the other versions are derived. An adapted version made with Luciano, the
author of GWM , is available for GWT . It allowsthis library to be used in a browser. NSTM is a .NET port based on IKVM.
All implementations are compatible with each other so object replication can take
place e.g. between a Java server and a .NET Smart Client.
- No plugins like Flash or Java required.
- Popup blockers are no problem. The content expands within the active browser window.
- Single click. After opening the image or HTML popup, the user can scroll further down or leave the page without closing it.
- Compatibility and safe fallback. If the user has disabled JavaScript or is using an old browser, the browser redirects directly to the image itself or to a fallback HTML page.
The Yahoo! User Interface (YUI) Library is a set of utilities and controls, written in JavaScript, for building richly interactive web applications using techniques such as DOM scripting, DHTML and AJAX. The YUI Library also includes several core CSS resources. All components in the YUI Library have been released as open source under a BSD license and are free for all uses.
Google Web Toolkit (GWT) is an open source Java software development framework that makes writing AJAX applications like Google Mapsand Gmaileasy for developers who don't speak browser quirks as a second language. Writing dynamic web applications today is a tedious and error-prone process; you spend 90% of your time working around subtle incompatibilities between web browsers and platforms, and JavaScript's lack of modularity makes sharing, testing, and reusing AJAX components difficult and fragile.
GWT lets you avoid many of these headaches while offering your users the same dynamic, standards-compliant experience. You write your front end in the Javaprogramming language, and the GWT compiler converts your Java classes to browser-compliant JavaScript and HTML.
