I'm a long term solidworks customer, (subs since '97) . Also a more recent twitter user [ @77A ]
I followed @solidworks and found it quite useful.
I also asked some questions about Solidworks strategy, and suggested that products like 'solidworks ID' and mech should either be integrated into solidworks or not called solidworks. I also questioned 'what is 3D experience ?' and asked when we will get the annual 'Top 10 requests' answered.
I may have used a swear word, once, "Catia-Lite" ....
Clearly @solidworks does not like any tough 'off message' questions, even from its customers ..... and they promptly blocked me !!!
Not a biggie .. I will live but hey, what's wrong with customer's feedback to improve product ?
[feedback on my products, even very negative is always welcome - helps make them better]
