Reason for checking for the presence of an attachment

[97-109-107]

When inspecting messages picked up in routes/feed.js I see messages like

{ type: 'message',
  user: 'xxxxxx',
  text: '<http://www.example.com/>',
  ts: '1458219053.000004' }

Which are naturally not represented in the feed because they don't pass through the next check: response.messages[i].attachments && response.messages[i].subtype != "bot_message"

I understand the rationale for the "bot_message" subtype being filtered out, but I don't get why the feed only seems to target messages which have attachments of links (how does that happen in the first place Slack-wise?)

Is this my misunderstanding, or did something happen to the api in the meantime?

I will commence work on making your application pick up any url present in plaintext of the users' messages, unless you say that's a dead end.

Thanks for sharing this, it already helped us a long way!
