Where do you look for experts when you need help ? For topics relevant to the Signal Integrity si-list seems useful. There are similar lists and forums for PCB Designs and other dedicated fields. The ezdia platform ( http://ezdia.com ) provides ability to get the help from an expert online. It is similar to LinkedIn but the additional concept of knowledge bucket. For example if you have expertise in Differential Signaling or SerDes you can associate the contents corresponding to SerDes in your knowledge bucket. When someone searches for Serdes, he can find an expert who has expertise in SerDes. You can then communicate with the expert to take his help.
