By adding a “buffer filler” number to my tweets for a day or two, I learned that IFTTT does *not* re-send tweets to Buffer when new buffer space comes available after it had reached its max.
In other words, any tweets triggered by IFTTT after Buffer’s tank is full will not be posted.
So, in order to make optimal use of the two services, I should fill up the buffer at approximately the same pace as it puts out tweets. Currently in my case, my buffer seems to have a limit of maximum nine tweets.
What I imagine I could do is to collect or prepare up to 9 tweets during the day and then add them to Buffer in the evening. They will be buffered and posted in spread intervals during the next 24 hrs.
It would be relatively easy to set up since I already created a “shadow” Twitter account to collect and prepare tweets. I can post those tweets from the shadow account during the day and then favourite the most interesting ones with my Twitter account @josschuurmans. Favouriting them will trigger IFTTT to send them to Buffer.
So next up, I’ll try and figure out a posting schedule that accommodates tweets with different levels of urgency.
