I have just uploaded some new code to hpoom so that you can now filter blog posts by tag as well as category. This is all part of the changes I have started to work on to update the site and give it a new look. I will now move on to redesigning the site and hopefully upload the new look site soon. In the mean time enjoy the tags method of browsing the posts on the site and have a play with the tag cloud in the side bar. I implemented tags with the help of FreeTag, check it out here
