Should Feed Readers Count Unread Items?

Brent Simmons, the developer of the NetNewsWire RSS reader, is questioning his decision to put an unread count next to each feed, reasoning that it encourages people to be too obsessive about reading every item:

Instead of a dozen bookmarks, people had a hundred feeds. Or two hundred. Or two thousand.

And there was a tyranny behind keeping track of unread items and showing an unread count. People reacted in different ways, but many people felt like they always had to go through everything.

Including me. To this day.

I did not know this was going to happen. That was not the idea: it was a side effect of reasonable (at the time) choices.

I like seeing these counts on feeds where I need to read all items that are posted, but that's only a small percentage of the 100-120 feeds I follow. It would be nice to turn that off for others I read more casually.

Feedly presents unread counts on each feed and folder of feeds. There's a Mark As Read button to clear a count, but when you click it, the confirmation dialog acts like it's an extremely consequential decision: "Are you sure you want to mark this entire source as read? This operation cannot be undone."

I've posed a question on the RSS-Public mailing list: Do you think feed readers should count unread items?

Tara Calishain Explains: What is RSS?

The exodus of users away from Twitter and Reddit has led many of those information refugees to discover the joy of subscribing to feeds in a reader. RSS and Atom feeds are an enormous open decentralized network that can never be ruined under new ownership -- because there's no owner.

Tara Calishain of ResearchBuzz has written a 4,000-word introduction to RSS for people who are new to the world of feeds:

I could not do ResearchBuzz without RSS feeds. They're invaluable. And I think if you learn more about them, you'll appreciate why I consider RSS the most underrated tech on the Internet. That's what this article is about: I'm going to explain what RSS feeds are, show you how to find them, go over some of the RSS feed readers available, and, finally, list several tools and resources you might find useful on your journey.

... I follow over a thousand RSS feeds which deliver information to me throughout the day. Do you think I could visit a thousand websites a day to check for new information? Even if I tried to visit a thousand a week that would be over 142 websites a day. Assuming it took me two minutes to visit a site and check for new content, I would spend over 4.5 hours a day just visiting websites.

Do you see why I'm so grateful for RSS?

Calishain, who was blogging before Netscape created RSS in 1999, covers a lot more than the basics, showing how to find hidden feeds on websites, check a bunch of feeds for freshness and create keyword-based feeds to search sites like Google News, Hacker News and WordPress. Even experienced readers of readers will learn new things, and there's a collection of nine handy RSS Gizmos she has developed.

On that subject, Calishain just began programming a year ago:

In spring 2022 I decided to find out if I could really learn JavaScript after being diagnosed as autistic. (I'm a high school dropout and didn't think I could learn something like programming.)

I CAN! And I LOVE IT!

Welcome to the not-so-secret society of programmers, Tara! Please slow down a little. You're making the rest of us look bad.

The Educator's Guide to Hashtags

Follow us on Twitter!  @CareerTechTest
Whether you're a social media novice or not, hashtags may seem confusing and inessential. These short links (hashtags) preceded by the pound sign (#) are integral to the way we communicate online and it's important to know how to use them.

Can hashtags be fun? Absolutely!

On Twitter, the pound sign (or hash) turns any word or group of words into a searchable link. This allows you to organize content and track discussion topics based on those keywords. So, if you want to post about the NFL Super Bowl, you would include #SuperBowl in your tweet to join the conversation (or simply search for the hashtag to follow the discussion). Clicking on a hashtag will allow you to see all the posts that mention the subject in real time.

I also recommend using a social media management platform, such as HooteSuite, TweetDeck, etc., where you can create columns with hashtag topics.  I like the ability to monitor several discussions, i.e. #edchat, #lrnchat, #careerteched, at once and all on the same screen.

I've created a list of popular educational hashtags and tried to categorize them for you (see below). It definitely isn't all inclusive, but it's a good starting point and I hope you will share any new educational hashtags you find interesting and helpful!  (Also, hashtags are now a staple to social media and their use has been extended to other social media platforms.)

Use Twitter "Moments" to Share School Events and Activities

Follow us! @CareerTechTest

Nearly a year after releasing its Moments curation feature, Twitter Moments is now available to users.

Twitter Moments are curated stories about what’s happening around the world—powered by Tweets.  Originally, a user could click on Moments on their profile page to find curated stories, i.e News, Entertainment, Sports, and Fun, in a typical news format.

But now, it’s easy to create your own story with Twitter Moments.  I think this is a great way to share school events and activities and it could also assist with classroom discussion, especially when dealing with current events.

Either watch the video by Richard Byrne of Free Technology for Teachers or follow the directions from Twitter below:


How to create a Moment

There are three ways to begin creating your own Moment. You can access Moments through the Moments tab, your profile page, or through a Tweet detail. To get started all you need is a title, description, Tweets, and a selected cover image.
