A minor update, but a useful new feature: subscriptions to both weblog and NNTP entries. Our advanced subscription page now includes a feedgroup for NNTP posts. Check the box to include newsgroup results in your subscription along with weblog results, or leave it unchecked for a standard weblog subscription.
Remember that with NNTP there can be a lot of spam and some crude language. Nevertheless, newsgroups offer a great deal of breadth and a lot of interesting content.
Try out a combined subscription, and let us know what you think!
PubSub's newest service lets you create susbcriptions to newsgroup (NNTP) posts.
The PubSub newsgroup service works just like our weblog subscription service - you can create subscriptions to the content of postings, and get matching results in an RSS file.
We've started with a small set of technical newsgroups (see the list), but we'll be adding more groups over the next few weeks. If you're interested in a particular group or set of groups, please let us know by email or use this form to request a group.
To create a subscription, visit our newsgroup subscription page.
Be warned that newsgroups are pretty raw compared to weblogs - since there's more anonymity in posting, people take more liberties than they would on their own weblog.
Newsgroups also contain a lot of spam. We don't have any methods for limiting this now, but we're certainly open to suggestions.
Please try our newsgroup service, and let us know what you think! You can always send comments to feedback@pubsub.com, or add a comment to this blog.
We recently added a field to our advanced search page that lets you subscribe to "Referenced URIs" in a document. (This field is available for REST subscriptions as well). Referenced URIs are links that appear anywhere in the source of an entry - as hyperlinks, images, or in the body text.
By subscribing to a URI (or part of a URI), you can see who's linking to your weblog, what movies people link to on IMDB, what books people link to on Amazon, or anything you can think of.
Subscribing to URIs is like trackback in real time - with a couple of extra features.
Unlike trackback, you can subscribe to a complete URL or just a portion of a URL. For example, you can subscribe to a specific item in a weblog:
https://www.pubsub.com/news/archives/000011.html
or to the whole weblog:
https://www.pubsub.com/news
You can subscribe to any portion of the URL, so you can create a subscription to image types (jpeg, gif, png) to retrieve weblog entries that contain pictures.
Best of all, you can subscribe to referenced URIs in addition to your other search terms - for example, you could subscribe to entries linking to Amazon that mention your favorite author, or you could subscribe to entries that link to your weblog that mention a specific topic.
Using Referenced URIs in your PubSub subscriptions can add a new dimension to tracking information. Not only can you find out what people are talking about, you can now find the connections between topics and put your information in the larger context of the web.

The newest PubSub service lets you subscribe to SEC/EDGAR filings in real time. You can be notified when a company or individual publishes an EDGAR filing, or when a particular form type is published. PubSub will notify you using an RSS file, or via email.
To try out the service go to https://www.pubsub.com/data/edgar and create a subscription. The subscription form tries to match the form available on the SEC website. If you need more information on EDGAR, visit the SEC's EDGAR page.
If you get a chance to try out the service, please let us know what you think!
We've recently added a feature, on the advanced subscriptions page, that lets you subscribe to all the weblogs we track - including LiveJournal, well over a million (1,000,000) feeds.
The standard subscription still uses our "low volume" feed, which includes roughly 100,000 source feeds. The distinction among the low volume and high volume feeds reflects the kind of data you can expect to receive.
We decided to move most of the personal journal type feeds into a separate feed group because there's just too much traffic for most people. Many subscriptions on the high-volume feed return 10, 20, 30 messages or more in the space of just a few minutes.
For most purposes, this can be a bit too much to keep up with. However there's a lot of great content being produced in these feeds, so we wanted to provide a way to subscribe to this data.
When you create a subscription on the advanced subscriptions page, you can indicate if you want results from our high-volume feed, the basic (low-volume) feed, or both. As we are able to categorize more feeds into distinct groups, we'll probably add several more options on this page. If you have any thoughts on feed groups, please let us know!
