After thinking about it a lot, I think the only scalable and reliable solution for this is to include the script in your template itself. So, I am asking you to click here and copy all the code from that page to your template itself before the
</head>tag. If you would prefer to upload the script to your server, use this code instead. This change is for the benefit of everybody from blogging community to make use of my hacks.
To get rid of the alert that you saw, please find and remove this line from your template (this is also important to help me retain my hosting account. thank you!).
If you are using my version of customizable recent comments widget (not Hans's), you should also goto this page and copy/paste the code before the /head tag. That should fix it.
UPDATE: Many of you have thanked me for providing a quick solution. There's a better way to say "Thanks" by adding a link to Hackosphere in your sidebar. When i visited some of the blogs using peekaboo posts, I didn't see any link to Hackosphere. Also, check out my new blog sharing website bvibes.com (if you haven't done already) where you can promote your posts and read/vote on other blog posts (it has 200+ registered users now).
