I'm writing a story for the BBC website about the changing climate on LinkedIn.

LinkedIn is beloved of recruitment consultants and social media advocates. But the world of excited career updates and triumphant business boasting has seen an influx of personal posts

Suddenly LinkedIn's messaging features emotional back stories. Posters offer up accounts of their childhood influences and admit to failings and frailties.

The hard-sell approach for CVs and companies seems to be crumbling and not everyone is happy. Critics murmur that much of this material is more suited to the family-friendly world of Facebook.

What do businesses and recruiters think about the warmer, more personal tone of the world's appointments page? Is this trivialising serious debate and does it risk lowering LinkedIn to the raucous level of Twitter?

I want to hear genuine opinions and personal experiences of posting and debate on LinkedIn.

I'm writing for the BBC on how cheap access to massive data crunching via cloud services has allowed market research to explore new territories. Assessing facial expressions and reading into the intonation of voice is now possible. But this takes up a lot of processing power and only the cloud can provide that at a realistic cost.

I'm looking for market research pioneers who have harnessed the potential of big data to learn new things about human behaviour. I want to show how they have opened their clients' eyes to customer viewpoints they never previously understood.

Please note, this is not a piece about technology products or a platform for tech industry opinions about future trends.

I only want to talk to people in market research who can flag up real, tangible examples of their achievements using this technology and exploiting the economics of the cloud.

I need to find individuals in marketing and advertising who can explain what the advent of online big data analysis has done for the quality of their customer insights. 

This story is now up on the BBC website, complete with insights into the link between Boris Johnson and Meghan Markle plus why you really loved that rom-com you claimed you snoozed through.

Are you happy using old technology for your life or work? I'm writing a piece on how outdated devices still suit their owners just fine.

Examples of this might be someone using a digital device from a manufacturer such as Psion or a venerable laptop from Toshiba. I want to hear about how this technology functions today and why you are attached to it.

I'm writing this story for the BBC website with a deadline for interviews of Wednesday 13 January.

I need one to one interviews with people who can be frank and passionate about why their old device cuts the mustard in 2021.

Please note, I do not require input from anyone telling me why their contemporary tech is so much better than the old school models!

This story can be read on the BBC website, complete with adventures vintage tech items undergo courtesy of helicopters and washing machines.

I'm looking for expert comment and practical insight into the race for hypersonic missiles and engines for an article on the BBC website.

I want to look at why hypersonics have proved so difficult so far.

I'm interested in the materials needed to protect electronics at these extreme speeds and temperatures. And I want to know whether some of the much-vaunted hypersonic weapons that Russia and China claim to have fielded actually work.

I'm aware of work being undertaken in the UK on hypersonic engines but I'd like to hear from any other company that thinks it can offer answers to the very specific problems thrown up by flight at hypersonic speeds.

There should be space within the piece for some discussion of the political and military imperatives behind this attempt to master a very challenging technology. So I'm open to thoughts and opinions on these dimensions of the hypersonic race. 

I'm researching this piece up until Friday 17 July.

This story can be read on the BBC website.
