As a social media, Twitter focuses on the principle of followers.
There isn't much point in making edits of pictures if the highres versions aren't available, since I don't want to redo them and adjusting proportions looks like shit with the lowres versions.
It encourages people to come to be amateur reporters of life, explaining and sharing something that they located fascinating regarding their day.
And no problem I'm glad you enjoyed the pic.
Daunted by this hectic network? The funny thing about it is how every time someone mentions it to him.
If you are tweeting in behalf of an organisation, job or team after that you might choose to just send out research-related tweets.
