Twitter has just enabled a new feature named “Lists” which permits to organize in categories the people you are following and make their tweets available to others. In this way it’s very simple to navigate the various subjects, follow the lists created by other people and subscribe to them.
I’ve tried this new functionality and created my own lists about Silverlight-related stuff, feel free to subscribe here if you find useful:
Pete Brown has posted two great articles about this topic:
The Social Web: An introduction to web 2.0 and its online communities, the new book by Marco Cantù, provides “practical information, links to useful sites, and all you’ll need to create or increase your online experience and/or presence”.
The companion blog is available at http://www.socialwebbook.com.
David Treadwell has posted an article in which he discusses new applications and APIs for the Windows Live Platform.
In particular he talks about:
New services & existing services progress (Windows Live Messenger Library, Contacts API, Silverlight Streaming);
Standardization of frameworks & protocols (Windows Live ID Delegated Authentication, Atom Publishing Protocol);
New pre-release services tools (Developer Tools – Windows Live Tools for Microsoft Visual Studio, Application Based Storage, Windows Live Photo API);
Windows Live Quick Applications (Visit Planner / Contoso Hotel, Tafiti Search Visualization).
In this article, Arun Gupta shows how to build Rich Internet Applications using GlassFish and related technologies: Metro, jMaki and Jersey.
