            If you add yourself to a list and then call the <a href="https://apiwiki.twitter.com/Twitter-REST-API-Method%3A-GET-list-memberships">get list members</a> method you might be surprised by the result.
            <p style="text-align: center; margin-top: 25px; margin-bottom:25px"><img class="aligncenter" src="http://images.raditha.com/blog/images/twitter/e4c5-lists.png" alt="Add user to a list"></p>

            One of the data items returned by the <a href="https://apiwiki.twitter.com/Twitter-REST-API-Method%3A-GET-list-id">get list id</a> method includes the number of members in your list. The <a href="https://apiwiki.twitter.com/Twitter-REST-API-Method%3A-GET-list-memberships">get list members</a> method returns 20 members at a time and you need to call the it multiple times using different cursor locations to retrieve the complete membership. When you count them and compare against the number returned by the get list id method, you will find that they do not match. Your own account is not part of the dataset that is returned.

            By the time you are reading this post, the list might have changed. So I have saved a copy of the XML <a href="http://images.raditha.com/blog/images/list-members.xml">here.</a> On the other hand when you access the list through twitter.com, you can see that I am included in my own list. In fact my screen name (e4c5) appears twice!

            The work around I suppose is to not rely on the members count returned by the get list id method.

            <a href="https://aws.amazon.com/ec2/">Amazon</a> has been offering cloud hosting services for longer than most unfortuntely they don't seem to have updated their Amazon Machine Images since they started operation. Well, it's not exactly accurate, they have reasonably upto date images for some linux distributions and for windows. However many of the linux images are actually owned by third parties and not by amazon itself. As for my favourite distribution Fedora, what's available is Fedora 8! After reading the discussion at <a href="https://developer.amazonwebservices.com/connect/message.jspa?messageID=141707">http://developer.amazonwebservices.com/connect/message.jspa?messageID=141707</a> I thought to try my hand at creating my own Fedora 11 or2 AMI.

            Unfortunately I didn't meet with a lot of success the Fedora 11 AMI refused to boot but trouble started even before, first with yum reported numerous depsolving errors. I tried to sort them out by using the --skip-broken flag to no avail.

                    Is this ok [y/N]: y
                    Downloading Packages:
                    Running rpm_check_debug
                    ERROR with rpm_check_debug vs depsolve:

                    (1, [u'Please report this error in http://yum.baseurl.org/report'])</span>

                I worked around this by uninstalling the complaining RPM (yum remove httpd-tools-2.2.14-1.fc10.i386) and putting it back after the upgrade had completed. Nevertheless the machine reused to boot up. I tried to do this as a two step process, stopping at F10, booting up that image and then upgrading to F11. Unfortunately that didn't quite work out either. The terminal displayed by the Amazon Management Console remains blank without anything ever showing up on it. Then I tried changing the RAM Disk and Kernel,&nbsp; tried&nbsp; using aki-20c12649 as the kernel and ari-21c12648 as the ramdisk with the same result.

                In the end I gave up on this temporarily and used a third party Centos 5.4 image (uploaded by <a href="http://www.rightscale.com/">RightScale</a>) for the task at hand. Going to come back to this problem later. Want to try installing a new image on the loopback device.
