Of course, there are many different types of individuals in a social media platform such as Twitter, and let's face it, for those of us who have a product or service to market, it's only natural to try to build our business and brand. However, as I connect with more individuals on Twitter, it's apparent to me that there are the polar opposites. My own personal pet peeve are those individuals where it's evident to me that their only motivation is what the connection can do for them. I suppose that I take it a bit too seriously, but it really gets my goat when I get an automated DM and they're just asking me to buy their book or like their Facebook page. At least to have the decency to try to engage me, to see where there are possibly collaboration opportunities. I'm probably a bit too judgemental on these automated DMs, but then again, there's that old saying about first impressions, and it doesn't leave a good one for me.
On the other hand, I'm really impressed with how there are those on Twitter that really understand the collaborative aspect of Twitter. All that one has to do is to read someone's TL and you can really get a sense as to how much the individual is connected with their followers. I've been pretty impressed with those that take the time to RT, but it reached a new level a few days ago where I noticed that an author was not only promoting someone else's work but was doing so not with a RT but by taking the time to compose a tweet and reference the author, the title, or whatever stood out for him. It might seem a little thing - I mean each of those tweets probably only took 30 seconds to compose, but their engagement shines through when I can see that they've been doing multiple dozens of these types of tweets over a short period of time. To me, that is exactly the type of person that truly understands what engagement is.
A tweet is most definitely limited by 140 characters, but the engagement and collaboration between people can be a long term thing.
