Twitter: black rectangles for some Discourse pages


(Graham Perrin) #1

The black lump and the texts that follow are for the third link, not the first, which is counterintuitive but I’m not here to fix Twitter :slight_smile:

For some types of Discourse content:

  • is the blackness to be expected when represented in Twitter?

This caught my eye:

– that’s about profiles, so I don’t imagine relevance to the black representation of a category, but I’m open to suggestions.

Side note

Yeah, I know, the vertical lines look bad in the shot above.

Cross-post (categorised as a feature) Image chosen for onebox / opengraph on category page is unexpected includes one additional item of background information. tl;dr an earlier view of the same tweet represented the first of the three links (not the third) and was not bugged by the blackness.

It’s a weird one. Not sure whether I should have begun this in FeverBee (where, I guess, people have more experience with use of Twitter to promote Discourse forums) or Discourse Meta. Apologies for cross posting.

All good. If you get an answer will you please update this topic for future posterity?

As far as I can tell, the only images are those that are usual for a category – logo, avatars and so on.

The black rectangle that appeared for https://discourse.opensourcedesign.net/c/feedback was https://pbs.twimg.com/card_img/863280008181239808/vRvsRZj3?format=png&name=600x314

I deleted the tweet where that rectangle was first seen.

There was a suggestion to use http://iframely.com/debug, all three links appear fine, there’s the logo:

Further experiments with the Open Source Design forum

The original tweet used all available characters (0 remaining), I wonderered whether that was a factor so I experimented with something shorter:

An experiment with just one link, surrounded by text:

A link – the forum home, https://discourse.opensourcedesign.net/categories – alone:

Experiments wih other instances of Discourse

I experimented with four instances. At a glance, none of the four is affected.

Mozilla Discourse

Note the generic icon for a page:

Not long after posting, Twitter begins to show a forum-specific image:

Something like the tweet in the opening post – three links, and the maximum number of characters:

Back to Firefox, where I made the first tweet about Mozilla Discourse:

After a simple reload of the page, there’s the forum-specific image in lieu of the generic icon for a page:

Next step

As I have not yet reproduced the issue with any other instance of Discourse, I raised the issue with local staff at the Open Source Design forum:
