You know, I wouldn't mind if you complained about things that actually mattered. But no, you like fixating yourself on the most trivial of things. You were led to believe that you can post a long title; then you found out that it doesn't display the whole title. Any normal member would take this as a learning lesson and ensure that he doesn't use long titles again. Why do you have to be bitter about everything?
Lets look at this from the other side. If we introduce a character limit on titles, we'll have someone (probably you) complaining that you cannot post long titles. The way things are now, at least a member is allowed to post a long title if he/she so chooses and in order to ensure that it doesn't break the page, the title is cut off and is displayed when you hover your mouse over it. This combines the best of both options. I quite literally don't see the problem here.
It matters to me, the consumer of the product on offer. Where are your business ethics, if you can't put the customer first?
Yes, it is trivial, and sorry if I'm not 'normal'.
'Learning lesson'? What? I don't want to have to worry about the system working properly every time I post something a little longer than usual. That's why I have come to this forum, for some 'support'.
'Lets look at this from the other side' ... it would be nice if you could!
'I quite literally don't see the problem here' ... and maybe that IS the problem?
You need to take the emotion out of it, and look at it professionally.
