Rory Cellan-Jones, the BBC technology Correspondent, is apparently the most visible person online in the UK according to the latest MostPublic Index due to be published tomorrow.

The NowPublic network, which acts as a detailed barometer of whose voices are the most heard in the digital landscape, reveals that Cellan-Jones is at the top of the tree as far as index is concerned.

The index works by gauging connectivity across four categories: online visibility, social networking and UGC presence, interactivity and microblogging impact. In other words, how your news and views are reported within networks such as Facebook, Flickr, Twitter, Alexa, YouTube, Google and Technorati to name but a few.

“The goal of NowPublic’s MostPublic Index is to measure—on a completely transparent, metric-driven basis—who has the greatest digital reach and is most effectively broadcasting their own personal brand online,” said Leonard Brody, CEO of NowPublic. “The UK Index is our first foray into analyzing the digital landscape outside of North America. Our neighbors across the pond have a history of early technology adoption and it’s clear that the utilization of leading US-based microblogging tools is no exception.”

A short, practical note on what a "most heard" ranking really means and how to read it.

As points out, MostPublic-style indexes aggregate signals from social networks, content sites and microblogs to estimate reach. That approach highlights who is being amplified across the web at a particular moment, but it is a snapshot — not a definitive measure of expertise or long-term influence. Platform selection, timing, and what signals are counted all shape the result.

Key limitations to keep in mind: these indexes favor people who publish where the tool looks (so niche communities can be undercounted); raw follower or mention counts can overstate influence if engagement is shallow or automated; and short-term news cycles or viral items can push someone to the top briefly. Measurement noise (duplicate accounts, API limits, differing site behaviors) also affects rankings.

Use the index as a starting point, not a conclusion. Cross-check candidates by looking for sustained output (bylines, long-form posts), peer citations, repeat mentions over weeks or months, and meaningful engagement (comments, discussion, linkbacks) rather than one-off spikes. For anyone wanting to replicate a sensible measurement: collect cross-platform metrics, normalize them to account for platform size, weight engagement over raw counts, and compare results across several time windows.

Finally, as reminds with the Ben Croshaw example, strong influence often lives inside vertical communities. Broad, aggregate indexes can miss that. For community-specific impact, track niche forums, comment threads, and recurring coverage in sector outlets rather than relying solely on broad social aggregates.
