personally for me, it helps a lot being a mobile app. i especially like the way it's designed currently with the lack of popups and glossy buttons/icons. i'm looking forward to the new features being added, but i can always use it on a mobile web browser in the meantime.
i'm often too busy with college to sit down at my laptop for long, which is why i like having that option. however, its a nice experience to just sit down at the pc and socialize idly.
for some reason, i seem to be getting issues with notifications... half of the messages people dm me arent notified for some reason. that's the only gripe i really have, but it might just be a me issue.
overall, to me it feels like an old iOS app. still fits within that older theme, as long as marketing doesn't get involved.
