What does Buffer do well? The best thing about Buffer is the number of accounts and posts that can be added. I don't get on the various platforms enough to post everyday, and Buffer makes it possible to bring a message to my audience on a consistent basis. It works with Pinterest and Instagram, but I only use it for Facebook and Twitter. Scheduling options and queue are presented well and easy to use. The way the analytics are presented. The content feed is also a brilliant feature, although it can also do with some significant improvements. This is by far one of the best low cost/free software's for Twitter, Facebook and LinkedIn posting.
What does Buffer not do well? I am very happy with everything that it offers, I can not negatively affect it because I have seen how they constantly correct all the inconveniences that arise. If I had to give criticism is that the content feed needs some improvement, as it does not always pull the most recent links. Addition of a filter for the content feed would be an A* feature.
What do you wish you had known about Buffer before using? Honestly there isn't a lot I dislike about Buffer. If I had major problems with it I would have switched over to Hootsuite or a similar app.
