Blogs, wikis, RSS, Social Networks, and all the rest are finally hitting the mainstream. You'd think I'd be thrilled...BUT OMG!!! When we say that blogs and wikis are another tool for your eLearning toolbox, we don't mean to say that you install a new blog, or wiki, for each learning solution/intervention that you implement. ARGH!!!
If your company has an enterprise wiki loaded up and ready to go...USE IT!!! Training/learning depts should be leveraging the technology, NOT creating it and maintaining it themselves (at least in most situations). Same goes for a blogging engine. If your company has an internal blogging system ALREADY for new employees don't give them another one to access and use JUST for your silly little training program. USE the one that's already provided!!!
Of course every company depending on its size has different situations to deal with. If you are a small company and your IT deparment is not supporting web2.0 yet, then you must take the initiative and do a little underground grassroots work. But don't forget your IT Buddy (if you've seen my presentations you know what I'm talking about). Making it happen can be easy if you have established an IT Buddy.
Remember, the difficulty of web2.0 is that you need to implement the tools first creating the infrastructure for use. This is counterintuitive to the traditional software approach. So, yes, you will run into resistance.
Web2.0 tools and their implementation is a complete PARADIGM shift...dang, I hate using that buzzword, but it couldn't be more true. YOU MUST THINK DIFFERENTLY!!!
