The key to successful leadership lies in being human. That's what Unilver's CEO Paul Polman deeply believes in. You wouldn't really expect that to be the most important attribute for one of the world's most influential leaders and especially for a male executive, considering how the general perception of a great leader is the domineering, command-and-control and know-it-all male.

But with the increasing requirement for full transparency, interconnectivity and a values-led approach, it seems that there's something missing in today's prevailing leadership style.

A "female" touch.

The social media world is moving so fast that we can barely keep up. Social networks are constantly introducing new features, improvements of existing features or even completely new designs (Facebook and Twitter). Keeping up with that pace and being in line with the latest change is a serious challenge for any person using social media for business or communications purposes.

Remember the social media cheat sheet I posted in January? Well, it's no longer relevant or correct. And that's just after 5 months. Nevertheless, I believe such infographics are extremely useful, which is why when I stumbled upon an updated and enhanced version yesterday I thought I had to share it with you.

Below you'll find an extensive infographic with all image dimensions for Facebook, Google+, Twitter, Instagram, Pinterest, LinkedIn and YouTube. The visual also offers guidance on the characters length for various posts, titles and descriptions as well as Facebook ads.

This is pretty neat to hang on the wall or save on your desktop and look for reference whenever you need a specific image or text parameter.

We all know what blogging is, but have you heard of vlogging – the abbreviation for video blogging? When was the last time you watched a tutorial on YouTube, for example a video explaining how to make a trendy hairstyle or how to build a website? We have all seen such videos, so even if you didn't know the term (and now you do), I'm sure you have experienced a vlog (i.e. video blog).

Vlogging - advanced blogging

What this means is that there are many people out there who, instead of writing long pieces and publishing in text format on a blog, create interactive video content on private YouTube channels, aiming at adding value for subscribers and not readers.

Among PR professionals these people are known as vloggers (i.e. video bloggers), or as they prefer to call themselves YouTubers.

Especially in the beauty industry YouTubers have become extremely influential making a pretty nice living only via vlogging. Sounds interesting? It sure is and this is what we are about to explore.

We all know about the many opportunities and substantial value social media provides for communications, marketing and for business overall, at least you should if you've been following my blog. What's still a grey area though is the adoption or rather acceptance of social media by the highest hierarchical level (if we can call it that way) in an organisation - the C-Suite.

One of the very fundamental things about social media is that conversations happen all the time, no matter whether you are listening, participating or ignoring them. This means that even if senior management is not following or engaging on platforms such Twitter, LinkedIn, Instagram etc. people are still talking and are by driving the conversation about the brand. Those conversations are often so powerful that they even manage to shape the brand's story and significantly influence corporate reputation. Isn't that a reason enough for CEOs to join the conversation and share their voices?

Apparently, for many it is not.

Last Friday I had the pleasure of participating in a brilliant workshop about storytelling, held by Petra Sammer, Chief Creative Officer at Ketchum - the PR agency the company I work for is proudly part of. As you have probably noticed, I have lately become quite fascinated with storytelling. It is currently my most favourite writing, research and learning topic, so coincidence or not, the half-day training took place very much at the right time, fitting perfectly to finishing my storytelling post series (at least for now).

I absolutely loved the workshop! Petra is such a nice person; she's extremely knowledgeable on the topic and she definitely has a way with words - she kept us interested during the whole time, not just with the stories she had chosen to show us, but the way she presented them.

Thinking about how best to present my impressions and considering one major takeaway from the session - the growing power of visual storytelling - I got a little creative myself. Making use of some of the slides from the workshop and the notes I made, I put together an infographic that summarises the key learnings from the training. You can see it at the end of this piece.

As I couldn't put absolutely everything in the infographic, here are a few more attention getters:
