Ensure Your Post Items Appear in the Correct Order

From developer.newsgator.com

RSS does not have any inherent ordering capabilities in the specification, just because you put items into a feed in a specific order does not mean they will come out that way after being processed by our (or any other) aggregator...

There are three ways to get around this.

• Use publish dates in the RSS feed.

By default, most aggregators order items in a feed by the published date, with the most recent content presented first. Note that badly formatted pubdates can be just as bad as not having a pubdate. We try very hard to parse pubdates, but if we can't parse your pubdate we will ignore it. To be safe you should conform to a published standard such as ISO 8601[1].

• Use NewsGator’s "Manage Posts" feature in Editor’s Desk to order content within Editor’s Desk. Administrators can order posts manually using the “handpicked articles” feature within the Manage Posts utility.

• Use Simple List Extensions (SLE) in the feed to create what is known as a “list feed”.

(Note that widgets do not honor SLE order. But a discussion on ordering posts would be incomplete without mention of list feeds.)

NewsGator's content platform supports Microsoft’s SLE extensions to the RSS spec. This is used to create a feed that acts like an ordered list of posts. Posts can be moved to different spots in the list (think of a billboard top 40 music feed).
