A bunch of years ago, before I was introduced to a small project called Google, I used to use Yahoo! for my searching. It was clean, easy and relatively well organized. It also had all kinds of great free services like personals, classifieds, e-mail, etc. But then Google came along, and started to gain steam, and I like many others left Yahoo for Google.
But Yahoo!, it seems, is making a comeback. First they bought Flickr - the photo sharing site, then they announced their new mobile tools at CES - http://go.yahoo.com (which alas, isn't available for my blackberry; during CES, they also went to MacWorld, to announce their partnership with Apple on the iPhone), and now they have come up with Pipes.
While Google has come up with tons of innovative ideas lately, this one is one of the greatest I've seen of late. What is pipes? It is a very simple tool that let's you combine website data - visually. For example, pipes can take a bunch of RSS feeds, mix them together and sort them so that you get a giant super feed, without having to a lick of programming.
The potential for pipes is huge, especially because it enables developers like me to do more with less work.
It will be interesting to see how Google answers Pipes!
