The reason I bring this up is that I have been asked those questions a few times and was wondering what I should do about it.
So, here is my response....
My actual work as an Escalation Engineer supporting Microsoft Dynamics GP keeps me fairly busy. Once you add the time spent working on the blog and responding to newsgroups as well as working on "pet projects" like the Support Debugging Tool, my time is well used up.
This means that I don't have a lot of time to invest in social networking sites. That said, if a social networking site can be used without requiring a large time commitment and can make it easier for people to connect with me... I'm in.
I have been on (click on the icon or link http://www.linkedin.com/in/dmusgrave) since November 2006. At this stage I am not on Facebook and think that the low maintenance, professional approach of LinkedIn is more suitable for me.
Now, what about Twitter. I can't see myself sending regular tweets via Twitter as I send enough information out via the blog, but..... Thanks to the magic of Twitterfeed you can link a blog's RSS feed to Twitter. So after being hassled by my brother-in-law for a long time, I have finally succumbed and created a Twitter account and linked it to the blog.
The funny thing is that within minutes of my first test Tweet on (click on the icon or link https://twitter.com/Dev4DynamicsGP) Mark Polino from DynamicAccounting.net fame had already signed up as a follower.
I still think that the best way to read the blog is via the website at http://blogs.msdn.com/DevelopingForDynamicsGP/. This is because using the RSS feed with a reader means that you don't see any edits made to articles after they are originally posted and you don't see the pages, news and links available in the blog's banner and left hand pane. At least the tweets from the RSS feed link you back to the original site for the full article.
We post content on a regular basis: usually Monday, Wednesday and Friday for original content and sometimes blogsphere or news posts on Tuesday and Thursday.
You can always come back every one or two days to check on the website, use the RSS Feed, or now you can also follow us on Twitter.
Let's see if this first post since setting up Twitter works....
PS: I have added the links for Twitter and LinkedIn into the left hand pane and the Blog's about page for future reference.
