Just came across this new product from google and no points in guessing that it is still in beta status the home page of the product is here with this launch by Google the trinity competing for the online gold are all officially in the rss mashup game now.
Yahoo has a product called pipes it is a neat little product built on top of plagger (read it somewhere cant remember where though) and YUI library for the nice ajax interface and the back end for interacting with RSS is based on plagger.
Microsoft has a similar product called popfly which is built on top of Microsoft web 2.0 framework which some people have called flash killer silverlight it is a nice little offering but the adoption is what is the worrying factor but with this framework going into some Microsoft products even the adoption of silverlight framework will pick up slowly and reach the main stream audience.
The latest entrant among the web trinity going for the gold pot in the online business is Google which is somewhat odd as Google is usually the first one to innovate the entry of Google also confuses because now it seems that Google can make money on monetizing this mashups with their latest purchase of feedburner as the other two in the game are giving this as just play toys to the developer communities of geeks who want a bit of extra power when dealing with their RSS feeds.
Well this trinity is after each others market share so it makes sense for them to launch copy cat products as soon as the others in the race do it as all are sitting on a talent on some smart engineers who can innovate as well as reverse engineer and improve upon.
