Typo cleanup repost:

I agree, but do note (as per my earlier response) the success of the LOD 
cloud pictorial as marketing collateral isn't something that's arisen by 
deliberate exclusionary actions on anyone's part per se*. Methinks many 
have simply slapped it into their presentations devoid of actual 
presentation goals. This single activity has helped and hurt the LOD 
cloud pictorial. Hurt meaning: creating the perception you describe above.

I hope not, and I don't think so. Even if it were to be true, would you 
blame the production of the pictorial for that? Really though, I don't 
recall anyone saying or implying that LOD pictorial is the Linked Data

1. Banff 2007 (Linked Data coming out party)  -- Chris was giving a 
DBpedia demo showing its inter-connectedness, TimBL then suggest to 
Chris to turn it into a cloud with periodic updates for demonstrating 

2. Richard (working with Chris at the time) picked up the challenge and 
refined the initial graphic

3. People started using it to show growth of DBpedia which also implied 
LOD cloud since the connections in the pictorial were reciprocal

4. Cloud pictorial caught fire re. powerpoint presentations + 
exponential effect of slideshare.

respective areas of interest, on an individual or group basis? **
