Just a Quicky?

This is just a quick one really. Well i say that, it might turn into a rant.

So one of the benefits of an increase in the media is new jobs, there are now job titles that never even existed before. Social media analyst? Search Engine optimization?

Now obviously in some areas theses jobs are needed, e.g. Search Engine Optimization is obviously very important to businesses as  it is proven that 70% of people will pick the first result on google and by the time you are at the 4th result you have lost 95% of your audience.

But have we now gone too far, it is obviously important that companies do have a social media presence to promote themselves, but does every company need a facebook and twitter?

A perfect example of this was something i saw at Liverpool Airport earlier this year, they have a 20 foot sign on the side of the car park saying follow us on twitter and facebook. I logged on only to realise that it is not following the airport, but in fact the airport car parking you follow on twitter. Now i feel that it is possibly a waste of money. Someone has to be employed to monitor and post on the social networks, that will be there whole job.
But it is a convenience, they have a captive audience. Its not a city center car park, it doesn't have any competition, and the public know there will be a car park at an airport. But still someone is employed to update a twitter that has less than 4,000 followers. Is that really an economical advertising solution?

Yes, it is great that media convergence and progression is creating more jobs
Yes, it is important for companies to have a social media presence
Yes, every company needs to advertise

But i cant think that every company needs to advertise in such a way.
