Hi, we have a huge amount of keywords to search against Twitter. We’ ve already had a small App to get data from Twitter stream using those keywords and we get about 15 tweets/ second. We have just finished another test app, using the same keywords but search against Datasift, We also got about 15 tweets/second.
For now, We’re not caring much about enriched information like Klout, Sentiment or Trend, so for our case, could you tell us the good reason to use Datasift instead of Twitter Stream API because personally we think Twitter’s nearly free of use. To use Datasift, I have to consume a cost of 300 DPU which we hardly afford.
