Not sure why this is downvoted, it's a valid point. It has become less of a utility. Facebook messaging is akin to AOL e-mail. Let me access my data and interact with my friends in a Google-way of efficient minimalism please.
I use FB to keep in touch with those I might not otherwise. But FB's messaging is horrible. I hate the fact that they keep all your old messages in a stream. Last week, I sent you a funny NSFW photo and this week I want to discuss business.
I don't want "messaging" to be a constant chat log. I want a UTILITY like gmail that works extremely well and allows me to contact friends & family in a central database.
Instead I get "Attachment Unavailable" when sending messages -- with no way of fixing it or understanding why.
I used to marvel at how awesome, efficient and effective FB was at design and coding. But now I'm more shocked at how stupid some companies could be like FB, eventually devolving into an AOL-attitude of stupidity.
Facebook = AOL of 2010s, it's better coded but equally obnoxious
