“Anyone who slaps a ‘this page is best viewed with
Browser X’ label on a Web page appears to be yearning
for the bad old days, before the Web, when you had
very little chance of reading a document written on
another computer, another word processor, or another
network.”

“[...] let me know what piece of advice you would give
to someone who will be graduating in a years time,
what would you suggest they are thinking about now to
help them be as employable as possible upon
graduation?
http://www.rachelandrew.co.uk/archives/2010/02/27/your-top-tips-for-students/


Love what you do
“I truly believe the most important thing a web
designer/developer can have is passion, because if they
are excited by something, they can learn it.”
- Ryan Townsend


Get real experience
“Get your hands dirty building and designing things that
see the light of day. Maybe its not a site, but an iphone
app, or contributing code or small UI enhancements to
a favorite open source project.”
- Chris Casciano


Your own site
if nothing else, start a blog and/or portfolio site – most
employers will be looking for enthusiastic and proactive
people, and a potential web designer who hasn’t got a
personal website is neither of these!
- Rick Hurst


Community
...take part in as many online communities as possible,
ask questions of other people about what you are
doing, help people out when they have problems you
know the answer to. This work will become your
’social signature’
- Tim Parkin


Networking
“Many web events offer good student discounts and I’ve
attended FOWD and going to DIBI for very reduced
rates and students should be encouraged to attend
these and any local events.”
- Graeme (current student)


Your Turn.
