Maximum entries in a topic rss feed
I'm not sure this is true, but observation seems to indicate that topic rss feeds never display more than 10 items. If you have a topic with a lot of feeds, and a RSS reader that doesn't refresh frequently - particularly web-based ones such as Google or Newsgator whose refresh frequency is set by the number of subscribers to a particular feed - it would seem that items could be missed. Can you confirm that this is the case, and if so, address the possibility of raising the number of entries in a feed, perhaps tuned to the amount of activity in a topic?

Inappropriate?Great idea -- we'll see what we can do.

Inappropriate?An update on this. This is definitely putting a serious crimp in the usefulness of topic feeds. Any fast-moving topic with more than a few sources will result in the vast majority of posts never showing up. Let's say Google Reader only updates my topic every 4 hours (I'm not sure if this is the case - if anything it might be worse, since personal postrank topic feeds would only have one subscriber and thus be de-prioritized for updates). If your topic has more than 10 posts in it a 4 hour window, you will never see them. For smaller, slower topics, that might be fine, but for high-volume topics with a large number of sources, it doesn't work well at all.
I’m disappointed

Inappropriate?I am having the same problem I think. This is a real pain and makes postrank pointless for me. The reason I use it is to try and manage the volume of feeds I would otherwise get in a sensible way. But even with postrank filtering there is still a lot more than 10 posts. My google reader only seems to check the feed once a day or so, so I'm missing pretty much everything.
Can you not track the last time the feed was accessed and simply display everything new since that time?
I’m annoyed

Inappropriate?Even if it just displayed everything posted in the last day, that would presumably cover the vast majority of posts and different reader update periods (I would imagine it is fairly common to check your reader once a day). A time based cutoff makes a lot more sense than a simple numerical limit.

Inappropriate?From your twitter message earlier: "we now support SUP (http://ow.ly/4ypI) for user activity feeds! developers, look at the headers to get started! #feature"
Is this for topic feeds, and if so, could Google be persuaded to use it? -
I don't believe google supports SUP, and our SUP integration at the moment is strictly for user activity feeds (not topic feeds). -
Inappropriate?I have been using several Topics for several days now, I feel exactly the same as these guys. Am I missing the point here? Why would anyone bother with Topics? If this is a known issue then why not be upfront and explain the limitations as well as when, in your opinion, it would be appropriate to use and what the users expectations can be. I can also vouch for a maximum of 10 posts at a time coming through my topics irrespective of how many feeds are within it or what type of content filtering I have selected.
-
Inappropriate?This should now be resolved! The number of returned items will depend on the number of feeds in the topic. Give it a try (albeit if you request the feed recently, give it 15 minutes for cache to clear).
