I'm fond of saying that social media doesn't have 'best practices' per se, we just have 'current practices'. Those things that we know are working right now with very, very limited play in a real market. That said, I see that Mitch Joel, Six Pixels of Separation, has started a blog meme on pulling together the best practices and has challenged bloggers to write one post. I also see that Toby has already contributed some outstanding insights. Here's my take

Social Media Best Practice Tip:

Alignment: Yes, that's it. Alignment. If your organization is considering (or is well on their way) pursuing social media in your tactical marketing plans. It (social media) MUST be in complete alignment with your strategy and differentiator as an organization and in complete alignment with what you're already doing in your marketing plan.

Strategic & Differentiation Alignment:
If you've not yet read Seth Godin's book, Meatball Sundae, I highly recommend you check it out. In a nutshell, it gets after this very issue. If you're in charge of marketing for any organization that does not (and is not likely to in the future) embody openness, sharing, trust and all of those things that are required in a customer-owns-your-brand world that is social media, this might not be a strategic fit for you. Should you change, perhaps, but that's not the issue here. Just as I would rarely advise a B2B startup client to advertise on network television, there are some companies that aren't going to align on social media. One last thing - even though your company has some aligning characteristics...if your legal department doesn't, your social media marketing plan may have a hard time getting off the ground. I'm just sayin'...

Marketing Plan Alignment:
This one's a bit easier, but still a challenge, and we're still talking about alignment. If you decide to setup a Twitter account because it's cool, but you're not blogging and you're expecting things to just explode for you, that's unrealistic (but, you already knew that...) You need to align social media vehicles with that you're already doing and plan appropriately for their launch. If you have a customer database but you've never sent an email, maybe do that first...then put up the videos, then email your customers again, then get the blog going, then seed you customers with that and get the real conversation going... I'm still bullish on data and collecting it on prospects and customers (RSS subscribers and video viewers are not success metrics in the end) and employing that data in your marketing and social media efforts.

[UPDATE] One more thing... This 'social media thing' is new, and it's not...you know what I mean...right? Well, here's what I mean. Companies that do well in social media are those same types of organizations with the criteria identified by Jim Collins in Good to Great. They would meet the test of social media readiness. Examples of that criteria include: humility, acting as a servant leader, being able to accept brutal honesty, availability, a willingness to share credit (ideally, give full credit to others) and take sole responsibility and blame for failures.
