PubDate/Guid is essential to RSS? How I create a good RSS in Yahoo! Pipes if the source doesn't provide different dates for the items?
I am creating a Yahoo! Pipe to a news site but the feedless source doesn't have a date/time for each item. My RSS doesn't works very well: each update makes the RSS Reader, Google Reader for instance, to mark all readed items as unreaded again. Perhaps that's because of the lack of pubDate tag or incorrect guid tag.
How to create a "pubDate" on Yahoo! Pipes when your source doesn't provide you the data?
How to avoid the "guid" tag overwritting? (you can set the guid in YPipes but then YPipes ignores your guid)
Solution: pudDate isn't necessary. guid is essential. Even if Yahoo! Pipes rewrites the guid, it will work, because Yahoo! Pipes converts your guid text into a hash value, that do not is modified until the text is modified.

Have you looked at Feedity - http://feedity.com - for creating custom RSS feeds. It's like Pipes, but much easier to use, and in fact works well within Pipes as well. I've been using it for a while to create RSS feeds for those "feedless" webpages.
