Listening to the
Six Pixels of Separation
podcast on my shiny new
iPod Touch last night, I
was struck by an item which highlighted the
growing use of hash tags. In this case it
was referring to an educational conference
held in Berlin:
#OEB08. Following the
eye-witness reports of the terrorist attacks
in Mumbai on Twitter a week or so ago, I do
recall seeing this reference to
#mumbai but gave it no
thought at the time.
I digress here for a moment or two. My flow has
been interrupted while I actually search for the
aforementioned key. It’s not displayed on the
Apple keyboard. A quick search on the web not
only reveals the location of # (alt+3 for uk
keyboards) but also that many others have
struggled to find it
before.
It turns out (and remember, I know there’s huge
numbers of you technical folk out there who are
saying right now ‘Doh! You don’t know that yet?’
I’m talking to the rest of us) that the # key
before a search term actually does a job.
This is how the site
http://hashtags.org explains
it: “Hashtags are a community-driven
convention for adding additional context and
metadata to your tweets. They're like tags
on Flickr, only added inline to your post.
You create a hashtag simply by prefixing a
word with a hash symbol: #hashtag.”
Hmm. Not sure I quite get that. Bit of real-time
research needed here. Been to
Wikipedia. A bit clearer,
but maths never was my strong point. A few
more websites later, it seems that, probably
stated too simply, the hash tag improves
searchability on a database. So if someone
tweets using # followed by a term, eg
Stephen Fry’s #oscarwildeday, and then
someone uses the same term in their tweets,
any searches will find all those entries
quckly and easily. Another report I found
about the use of hash tags was by
anti-bullying site
BullyingUK.
And of course, for every idea or innovation,
there’s always people who see the
negatives. As It happens,
I think Paul Nich makes a good point here in
his explanation that hash keys only work
well when the group is big. He suggests
another solution for smaller groups or
organisations.
So, I’ll be trying a few # searches over coming
days and I’ll let you know how I get on.
