Since Google acquired Pyra, there's a note on the blogger website that they no longer offer BloggerPro and will fold most features into one product.
So I'm really curious as to whether this new product will offer categorization. I'm already thinking that I don't want to wait too long for that feature, because I have experience with the nightmare of having to catalog stuff "after the fact," or change a cataloging system in mid-stream. The more items building up in a collection, the less likely anyone is going to be willing to categorize stuff - it can all seem so daunting.
It's funny, my brother and I both work in the information retrieval field, but he has ended up working on perfecting search as a tool, while I'm a big supporter of browsing as an equally viable option (studies show ... blah, blah, blah). Not that he is anti-browse or anything, but it's still interesting that Google embodies the "search is king" philosophy while slightly downplaying the directory option they offer. I think everyone is excited about faceted classification and the way it can support BOTH searching and browsing, yet where are the best practices and tools to implement that approach?
