This might be interesting for the TAG.
A paper about short URLs and their impacts on the Web.
http://research.microsoft.com/pubs/144777/fr351-antoniades.pdf
I like one of the comments which is
Surprisingly short URLs are not ephemeral,
as a significant fraction, roughly 50%,
appears active for more than three months.
I wonder if I would define three months as long. ;) but I guess it depends on the context. It is true that three months might be long compared to the peak of buzz related to sharing one URI for a few days or even hours.
Intro from
http://research.microsoft.com/apps/pubs/default.aspx?id=144777
Short URLs have become ubiquitous. Especially
popular within social networking services, short
URLs have seen a significant increase in their usage
over the past years, mostly due to Twitter’s
restriction of message length to 140 characters. In
this paper, we provide a first characterization on
the usage of short URLs. Specifically, our goal is
to examine the content short URLs point to, how they
are published, their popularity and activity over
time, as well as their potential impact on the
performance of the web.
Our study is based on traces of short URLs as seen
from two different perspectives:
i) collected through a large-scale crawl of URL
shortening services, and
ii) collected by crawling Twitter messages.
The former provides a general characterization on
the usage of short URLs, while the latter provides a
more focused view on how certain communities use
shortening services. Our analysis highlights that
domain and website popularity, as seen from short
URLs, significantly differs from the distributions
provided by well publicised services such as Alexa.
The set of most popular websites pointed to by short
URLs appears stable over time, despite the fact that
short URLs have a limited high popularity lifetime.
Surprisingly short URLs are not ephemeral, as a
significant fraction, roughly 50%, appears active
for more than three months. Overall, our study
emphasizes the fact that short URLs reflect an
“alternative” web and, hence, provide an additional
view on web usage and content consumption
complementing traditional measurement sources.
Furthermore, our study reveals the need for
alternative shortening architectures that will
eliminate the non-negligible performance penalty
imposed by today’s shortening services.
