You're right, I did phrase that improperly, thanks. But a time series of three days is so close to useless it's hardly worth discussing.
it's sort of liking saying "Albert Pujols had multihit games on April 14, 19th, and May 16th, so he must be having an awesome year!" Not.
And even if the trend is more absolute postings, unless it's proportional to the growth of the community it doesn't mean a thing.
So, more data please!
