Yahoo Pipes Vs Google Mashup Editor
Finally I made time to try both Yahoo Pipes and Google Mashup Editor(GME). Both the things are cool in their own way, but Yahoo Pipes are for Laymen, anyone who are familiar with feeds(atleast if they know how to use that), they can easily work with Pipes, but this is not the case for GME, one should know XML to build mashups. So from a programmer’s perspective, GME sounds better, but Pipes had made it easy go. And Yahoo Pipes is a hit when compared to GME, because of its GUI, which has a higher reachability level.
So many tutorials are out there in the net for this, infact both of these services have their own tutorial, yahoo here again comes up with a video tutorial, which is good enough to get started.
Pipes has some limitations, you cant think out of the box, you are allowed to play around only with pre-defined options, as GME is code based, you dont have this limitation, which makes GME more flexible. May be some IDE will helpĀ GME more successful. We have Microsoft Popfly another equivalent, but its still in alpha, lets wait and see what’s Microsoft answer for these.

AlchemyPoint is another mashup platform that was recently released. It doesn’t require knowledge of XML or XPath like a lot of other mashup editors.
I would love for you to try out Popfly as well. Though we’re in alpha, we send out ton of invites on a regular basis so you can just sign up on the site and get on very soon. Or send me a mail at sriramk@microsoft.com and I’ll make sure you get one
