I don’t have much time for it and I’m no expert but I do get that others see personal and commercial value in it. The very fact that people may be talking about you or your business on it means you need to adopt some sort of position - don’t you?
As far as Recruitment Consultants are concerned I see no value in it directly. Will you attract candidates? Will you attract Clients? Will you shape your brand? Is anyone listening? Probably not!
However there are a number of interesting services for Recruiters that use Twitter to deliver. www.twitjobsearch.com . This may have some value for you?
Twitter propagates messages fast and people can say anything about anyone. However it’s the bigger names that are talked about most so if you’re a 2 man Agency from Doncaster and you don’t kill your candidates the chances are no-one is going to care or talk about you.
As most of the recruitment sector is made up of small agencies this is the problem with Twitter if you’re looking for a commercial channel. The only time it requires your attention is if you’re a mega agency or you join a twitter job board or you overcome the fact that you have a very low profile by forming/joining something bigger.
Otherwise it's a waste of time.
