Twitter is a great place to learn and stay up to date about SAP. You can easily scan a lot of messages and drill down on what you want to learn more about. I thought you might like to see ten Twitter people in the SAP ecosystem who I get value from following, partly to thank them for keeping me posted and partly to help you if you want to learn more.
Andy Klee (no relation) runs an ERP training company and has a great sense of humour.
Example tweet: Is paying maintenance as a % of the full price of the software like tipping on the full price of a meal before the half-off coupon?
Chip is one of the senior managers at SAP, he's in charge of the community (all 2.4 million of us) and much else and seems to always be on a plane. But he's insightful on technology and also shows you where the heart of SAP marketing is.
Example tweet : Excited to see Sting perform at #SAPPHIRENOW, world’s premier business technology event, on May 18. http://spr.ly/6014uCLk
Greg runs marketing at SAP Business ByDesign, his tweets are interesting because he's one of the team in the process of changing SAP from just On Premise to software as a service too.
Example tweet : Listening to large enterprise customer talking using #ByDesign in a subsidiary. "Its different from big SAP, but the genetics are there"
Jon Reed is a serious US-based blogger on SAP and very well-informed on what is happening within SAP. He is an SAP Mentor and an independent and credible analyst.
Example tweet : #SAP's Tobias Dosch leads Wallforf teams for Career OnDemand/Travel OnDemand, next 2 LOB apps scheduled- target rampup 2nd half 2011.
Natascha works for SAP and is very sharp on social media, she seems to be absolutely on the pulse, a real expert.
