Buffer used to be really good. A productivity booster. We've been a customer for four years. However, in recent times using it has become as slow as watching paint dry. We had five or six sets of 12 items each that needed to be tweeted in a specific order at specific times. It was taking between 4.30 minutes and 7 minutes to reschedule 12 tweets. To queue up 100 Tweets -- we would send 48 in a 24 hour period -- would therefore take a minimum of 40 minutes per channel. Scheduling became such a PITA and so time consuming that we cut our schedule to just 25 Tweets in a 24 hour period, and our LinkedIn posts from 12 to one. If something was misscheduled deleting more than one or two scheduled posts became a total head fck unless you work at a speed of about one deletion every 30 seconds. The site now appears to suffer from processing and memory insufficiencies, with tech support totally ignoring the slowwwwwww processes demonstrated to them in videos and attempting to lay the blame everywhere else, except at its own core. From being an application that (I and) the staff enjoyed using, it became one that they (and I) totally detested because it was so agricultural and time consuming.In the wake of completing this review I returned to Buffer as a free user. As if the queueuing process wasn't slow enough before, reposting a previous sent item to Twitter now displays a preview of how the tweet would look SLOWING THE entire process down even more. This is totally, absolutely ridiculous and shows that the developers have absolutely no understanding of the word productivity. Just don't waste your time. This is total crap now.
