It is Interim, not long-tail or glitches

A few months ago, IT-Sideways' Google Pagerank has been reduced from 4/10 to 1/10. We consider it as a dispute and calling it either due to long-tail, glitches or just interim process.

Now, the pagerank for IT-Sideways has been reverted back to 4/10 as according to the measurement provided via iwebtool.

Thus, this proves that it is just an interim adjustment arised from Google's system.

Or could it be other reasons ?
