This may be a duplicate but it's rather odd that I can post as many characters as I want on someone elses profile but I'm limited to 140 on my own. I propose making it the same for both. Either not limited on my own, or limited to 140 throughout (I'd actually like to see this number increased if that's the route taken but that's another issue).
I guess I think it's worth posing a question, just for clarity's sake: Why was the decision made to have a distinction between a "profile post" and a "status update?" What advantage is there to split the two - why not just have profile posts at 420 characters, or status updates at 140, and just have one?
I'm not really taking sides on this, I'm just curious as to the rationale behind the system as it stands now.
Without having a blog feature in XF, my members would have to use their profile walls to post information and updates for only their friends (no, those they have to follow) to see. Videos and pictures are a part of that information.
