After a long period, I just built packages of microblog-purple and Mitter for Ubuntu in Personal Package Archive. PPA is a kind of personal repository for apt-get hosted at launchpad.net. As a result, you just need to add below lines to
deb http://ppa.launchpad.net/sugree/ubuntu hardy main deb-src http://ppa.launchpad.net/sugree/ubuntu hardy main
And simply run
apt-get to install.
sudo apt-get install mitter
sudo apt-get install pidgin-microblog
I guess you should already know that I got Aspire One A110 to try for a week and I posted the review based on Ubuntu Hardy 8.04.1 at Blognone. I have lived with Aspire One a few day especially today I took it to try outdoor in practical usage even tweeting while walking.
Honestly, I really love Aspire One but I can't buy it. So I have to find reasons to tell myself not to buy Aspire One.
microblog-purple supports 2 platforms, Windows and Ubuntu. However, you may compile it yourself on your platform. The first version is 0.1 came with load of features that you missed for so long.
