Did you notice it?
Sometime yesterday (August 12, 2015) Twitter removed the 140-character limit from Direct Messages (DM).
Shout it from the rooftops. This is great news!!!
Unfortunately, this does not affect regular tweets. Tweets retain their 140-character limit.
Why this is good news:
Twitter DMs are no longer limited to the 140-character length.
It means that you no longer have to send multiple DMs to get your message across. You can type your whole message into 1, single DM. No more reviewing and cutting back to make the old 140-character limit.
It appears that you now have 9999 characters in a DM. Use them well and wisely.
Why this is bad news:
Those whom you don’t know, don’t care about you, and only want to sell you stuff will take advantage with a longer sales pitch.
However, it’s not-that-bad. You may still delete a single DM just as easily as before.
