Meetup has removed the submit button from the comment form on each group page. As a result I see lots of comments where someone hit enter, hoping to create a new line and the message gets submitted with only half of what they wanted to say. This is a bad user interface design. The submit button isn’t ugly and removing it might make it seem more simple and cleaner, people expect to hit enter and goto a new line in a textarea box. Sure the enter key is used for submitted a form but not with the textarea. It seems they also removed the ability to edit a previous comment as well. I’m guessing they picked up this idea from another site, but I haven’t seen it done elsewhere.
