With Buffer you can add a lot of tweets into your queue of Buffered Tweets, without flooding your followers.
The website for Buffer has been out for a while though until recently I never really paid it much attention. The concept is good as it saves you from spamming the timeline of other people on Twitter. Instead of sending out a dozen or so tweets in a row and then going silent for the rest of the day, Buffer makes it easier for you to spread these tweets out during the day. On the Buffer website, you can set up certain times during the day when you want tweets sent out. Then, as you write tweets, it will go into this queue and will then be automatically sent out at the appointed time.
A few days ago they brought out the iPhone app for Buffer which is when I started to play with it. From what I have seen so far, I do like it a lot. Early in the morning, when I am feeling more inspired, I can enter a series of tweets and these will then be sent out during the day. I like it that you also have the option to change the order of the queue or change a scheduled time to send a tweet out straight away. There is a workaround bookmark that you can set up for your favourite browser. When you choose this bookmark while browsing a website that you want to tweet about, you are sent straight to the Buffer app and the title and link is there waiting for you. One thing that it doesn’t seem to have yet is the ability to change the time within the app. You need to go to the website to do that.
