It's not the same. For example you posted a picture with some food you bought. That gives me a picture of food from a German household that i had no idea, which is interesting. Then you said the strawberries cost 14€ the milk 1€ etc. And i wondered, how is that eggs in countryside in Germany are cheaper than here? What's going on? 
All that needs interaction.
You only have to interact in the end, posting is just a start and bots can't do that
