I have never seen an upgrade to any app or Site that actually improved things. All they do is change formats and add additional buggy features in lieu of fixing the original issues/bugs. Then again, I've seen the way the techie crowd drives so it doesn't surprise me that they're just as oblivious to every other aspect of the world too.
Instead of bells and whistles that do nothing (if you were all in charge of hardware, you'd be converting Crays to TRS-80s):
Make embedding videos a lot easier - automatic with just linking to the video. Facebook does this - so can you.
Do the same with photos. You should be able to upload direct from phone/file.
If you're going to switch to those emojis, add a shitload more. Better yet, just bring back the old ones, including the smirk and beating of dead horse.
