I clicked the feed a couple minutes ago ( https://www.newsblur.com/site/5624839… ) and then when I clicked it or shortly after, the title changed to Engadget RSS Feed (the default title of the feed) with no favicon and there were no unread stories. Then when I tried to reload newsblur, it said newsblur was down. After waiting a minute, I reloaded newsblur and it was back, the feed reverted back to just “Engadget” and it had the most recent 26 stories as unread (I had previously read most of them) Additionally, if you switch the view to all stories, they are all gone, its only those 26 most recent (plus ones coming in new now)
Looks like https://www.newsblur.com/site/1498485… is the correct rss feed for engadget.
Be that as it may, why did the history get wiped out? If you look at the statistics for it, there are still the year(s) worth of accumulated tags, just not the old stories. Also, what constitutes the correct feed (and this is not your problem)? Although I have seen some sites where it has a link to its own domain which redirects to a feedburner, and its unclear which link is “correct” or which you should choose, in this specific case, the engadget rss link (at the top of the homepage under the “More” menu heading is http://www.engadget.com/rss.xml as opposed to the one you linked (though they are ultimately the exact same)
