A lot of y'all have personal sites. Personal sites with portfolios. Or you work for or own an agency where showing off the work you do is arguably even more important. Often the portfolio area of a site is the most fretted and hard to pull off. Do you link to the live projects? Screenshots? How many? How much do you say? How much of the process do people care about?
I'm afraid I don't have all the answers for you. I don't really do much freelance, work for an agency, or have a need to present work I've done in this way.
But! I tweeted this the other day:
Build your case studies as microsites. Then they can just live alone and don't have to be a drag when redesigning your site.
If the microsite gets old and stogy, the project you're talking about probably has too.
I remember working on that microsite. It wasn't a burden, it was kinda fun. We built it as we went, when all that stuff was fresh in our minds. Now that site is kind of a monument to that project. Nobody needs to touch it. It doesn't load some global stylesheet from a main website. It's a sub-domained microsite. It'll be useful as long as it's useful. When it's not anymore, stop linking to it.
I've also watched loads of people struggle with what to put in that portfolio and how to deal with case studies. I've watched it be a burden to people redesigning their site or building one for the first time. I've also looked at a lot of personal sites lately, and the default is certainly to work the portfolio into the site itself.
Maybe for some of you, making your case studies into these microsites will be a useful way to go!
