Problems of a starting lecturer

Some time ago, in Capturing an Emotion post I was writing about solitude. Yesterday, dr Mari Karm was giving her venia legendi about issues that starting lecturers encounter. The lecture, introducing recently started research about 'young lecturers' (btw, it's very problematic to define young lecturer as very often they've already been giving lectures before officially becoming a lecturer), was very much like a response to problems I've outlined in that post mentioned earlier. That solitude (either physical or mental) is surprisingly familiar to people in this group - when they try to apply novel teaching methods, to step out of the box, they may meet resistance both among students and colleagues; when they want to ask about some issues, all others seem to be in a hurry so they have to decide themselves, etc. She also added the 'frog pond' issue - at University of Tartu, which may sometimes be the only place where some curricula are available in Estonia, many young lecturers are actually former students from the same university, and exchanging the 'hat' of a student for a 'hat' of lecturer and colleague can be very challenging. Of course, what Mari Karm did not mention, is the rivalry between Estonian high schools and/or universities - there are some people that contend that there's only one university in Estonia, and of course, in their opinion, it is the University of Tartu (others are high schools). Well, IMHO this kind of attitude does not help to increase 'migration' between universities, when for vacant posts people from 'own' university are preferred (they are better familiar with the institution, yes, but constantly reproducing the system without considering alternatives is not too sustainable, I'd say). Even in a small country like Estonia there are still issues of matching degrees in overlapping disciplines - as a 'migrant' myself I know it well. It is doable but it takes time to gain trust and overcome other barriers. So when there's a possibility, it's easier to stay. During the questions' round dr Mari Karm mentioned that it is really not so in many other places where people are nearly pushed to start an academic career in some other institution. I wonder, is it so because of the lack of positions 'at home' or is it a calculated decision to allow some 'rotation of knowledge'? I wonder, whether the 'newcomers' are accepted quickly (as it is said to be like a norm) or reluctantly (as they are still strangers, despite this tradition)? I'd be happy to get personal insights to this matter...
