Since I'm in my current company (more or less 6 months) i introduce some interesting things
After every deployment (every two weeks on monday) the day after we review the last artciles and interesting things to share. We have a shared folder of google docs and I put all the links inside one document at every meeting
Another things it's to go to the meetups, sometimes i go alone and other with my coworkers
Define a roadmap of things to do, and to refactor, implement and to have the app up to date
I propose a migration to a cloud service/hosting and now we are contacting some hosting companies and viewing the best choice
For my own i read articles, go to katas, workshops, meetups, make networking and see what it's the new an interesting in the market.
For other side ahead of only development team, in my company make once a month a monthly meeting to have feedback and share of every department.
If you want to know more say me anything :)
