@Temery This is first time you reply to my post so while I deplore the general tone, at least maybe we can have a conversation.
As you can see in this thread, I try to reply to every message here shortly after they are posted. This thread has over 2,500 messages and I've read every one of them. Whenever an issue arise, I will work with the original reporter to find the root cause and whenever possible, fix it in a timely manner. If my replies and requests for information go unanswered, then not only does it mean that my time was wasted, it also means there may be an issue that will go unresolved.
The first two times you mentioned having troubles with Twitter I went on my own and tried it on a variety of browsers/OS combinations. It worked every time. The URL you mentioned isn't publicly accessible but there are other threads in the public parts of the forum that contain embedded tweets. Today I tried visiting one of those using a virtual machine running iOS 9.3 for the iPad Retina browser, as well as Internet Explorer 11 on Windows 10 and Internet Explorer 13 on Windows 10. They all displayed the full tweet as expected. I simply cannot reproduce this issue on my own.
There is exactly
one way to ever see this issue resolved: by getting hold of a user actually experiencing it. The issue is almost definitely related to JavaScript and there should be an entry in the browser's error console. It can be caused by any number of external factors, especially by extensions and sometimes by antivirus software that would incorrectly prevent JavaScript execution. If you can find someone who has troubles with embedded tweets and if you can get them to look for errors or security warnings in their browser, then it will be a step towards fixing it.
If you are looking for other forums displaying embedded tweets, you may try
this one.
