experiment with categories

I have experienced with one method of using del.icio.us for Blogger categories (explained here). It's a Java script (bookmarklet?) that makes tags for Technorati and del.icio.us, to which the categories then pile up and link back and forth to Blogger. When you write your next blog post, click on the tagmaker bookmarklet, enter keywords that refer to the post (separated by a space only), click OK when you're done. The bookmarklet will automagically select the code for you to copy, & then you can paste the resulting code into your post. Your post is tagged. Now publish it & go to the permalinked post page for your new tagged post. Copy the keyword tags out of the post and then select the del.icio.us post bookmarklet. Add the same tags that you put on the post to the form, removing the commas if necessary, and save your blog post on del.icio.us. The category links that I have in the side bar to the left I've just done directly to the Blogger template; there seems to be scripts for more technically savvy ways to do it, but by now I'm fine with that. Now I have one question to native or near-enough-native speakers of English: is at the correct preposition to have in "Categories at del.icio.us/hunjang"? Categories at del.icio.us/hunjang: technicalities • blogging
