The activity feed in SharePoint 2010 is very interesting. It is a way to see and read what your co-workers are doing. Most of your actions in SP2010 will end up in the activity feed.

But what about your actions and updates outside the organisation? Like twitter?

Stef van Hooijdonk created a class that will import your twitter updates ( through your public timeline rss feed ) and will post those updates to your activityfeed. Form more information and download; click here...

jQuery is a fast and concise JavaScript Library that simplifies HTML document traversing, event handling, animating, and Ajax interactions for rapid web development (wikipedia article). It was created by John Resig and dual licensed under the MIT License and the GNU General Public License, jQuery is free and open source software.

Marc D. Anderson developed a jQuery library names "jQuery Library for SharePoint Web Services" which abstracts SharePoint's Web Services and makes them easier to use. It also includes functions which use the various Web Service operations to provide more useful (and cool) capabilities. It works entirely client side and requires no server install.

You can download it or you can read blog posts about this project(on Marc D. Anderson's blog)

ASP.NET sites after a long period of inactivity, the site comes up very slowly during the first access. However, subsequent accesses, by same or other users, are fast. More than people know that is an IIS setting issue (goes to sleep!). However, the slowness is not IIS.

The first request to an ASP.NET application is slow. The reason you see this repeatedly is because IIS (which I assume you are using) will idle timeout when the configured time is reached If you don't want this behavior, and you do not need IIS to shut down the application pool, you can disable this.
But there is nothing in IIS you can do to solve the actual problem that First request to an ASP.NET application is slow. SpSiteWakeUp is an opensource tool allow wake up your SharePoint sites and sub site. You can use Windows Service version to automate this progress.
