SSL, trust me I felt the same way - someone mentioned this first on Contractor Talk & my response was that it had no value that I could see & I made the joke about tweeting every time I hit a nail & finished off with Ouch, never tweet while nailing
Now, not only have I made more contacts with people in the industry, but with lawyers, designers, architects, etc... & low and behold for all the jaded among us - actually gotten work from it, same with posts made in other forums, my blog, etc...
Now is this for everyone - no
Should you treat it as a sales platform - no, because it isn't, but as I stated above you can get actual leads & sales from it - with your evangelical approach to SSL, I think you would be amazed at how many people would follow you, and help you out
If you can approach it with an open mind - check out Amy Good's presentation on Twitter http://mynetwork.yourbuilderlink.com/pg/pages/view/15206/
