Everybody's favorite Peekaboo posts has been improved once again by our beloved Hans! The only thing that I was not comfortable about peekaboo was that after collapsing back an expanded post, the page showed totally different posts which was a bit confusing. With Hans's improvement, the collapsed post's summary will be the one at the top of the page indicating where you were before clicking "Read more". I have incorporated this improvement in my hackosphere.js file.
Good news is that if you have applied Peekaboo hack already, your blog will exhibit this behaviour without you making any changes (the magic wand of Hackosphere will take care of this :)). Hans also has another suggestion if you would like the post title & summary to appear at the top of the page. If you prefer that way, check out his post.
