I think this is a very interesting and thought provoking blog...
I agree with CarolA3 regarding the point that there are thousands no doubt who are trying to do their best from a distance and so this can't be classed as a 'sin'. I am very fortunate in that I happen to be in an area that the majority of my ancestors settled in so it is easier for me to visit local archives and libraries to find family records.
However, it is not possible for me timewise or financially to swan off around other places in the country or even abroad to places like America where some of my ancestors went so it is great that we have the internet these days and forums like RootsChat to obtain help.
If it is possible to walk in the footsteps of our ancestors - I would definitely recommend this too. A couple of years or so ago, I went to visit the Half Moon pub in Durham which my Ancestor Edward Senior was publican in the early to mid 1800s - this was fascinating to look around and to see where they actually lived. The staff said it was alright for me to take photos too.
Personally, I think chatting about genealogy is a virtue rather than a 'sin'
; however, I know there are a number of very strange people out there who would disagree and likely find this boring.
I suppose I can understand - I have no interest in football or fishing for example - and if others started talking about these hobbies I would likely find this boring. I am one of those people who is very interested in how I got here - what paths were walked to get us here, etc. So not easy to fathom why others might have no interest - but each to their own.
I also strongly agree with helping others. I think there could be a blog in itself on how people can go about doing this. For example putting postems on freebmd entries is an easy way to share what knowledge/records you have.
