The following message has been given to us from the PeerIndex team:
Hello to tCn members and all those connected…
One of the great things we’ve been privileged to watch is the emergence of the self organised professional communities within Twitter (and social media). tCn – the Construction network (@tCntweets) and the Built Environment community more generally is a strong leader in this trend.
The PeerIndex groups and ranks have fed into this to provide additional tools for professional communities. Recently, there has been some wobbling in our ranks, including rises over a period of two weeks, followed by falls.
It’s not you. It’s us. We recently increased the number of profiles we index to 45 million – and needed to make adjustments to various thresholds that assign scores to you in topics. One consequence of this modification is to cause some people’s PI ranks to shift.
We do modify thresholds as we adjust to the increases in data and changing behaviour of spammers and bots. We are working on a system that will alert you to these changes as they are made to increase our transparency.
It is obviously important that we maintain consistent stability of rank presentation. However rest assured, no data was lost and all that changed was a systematic change of people’s ranks across the board, rather than any relative changes.
Here at PeerIndex we are keen to help those connected to tCn and the Built Environment community better understand social media so that you can gain the most from it.
