It's great that you mention the dead links, I did notice it but never even thought of mentioning them. True though, you want the first impression to be a good one and in this day and age that first impression is often through links provided in an article. Great post @anouk.nox!
Yes, I really feel it's important to correct that. It would be such a shame if possible clients lose their interest when seeing that the last updates are from summer 2018. The twitter link I changed to the working twitter account (like you mentioned), but there's no activity there either. Hopefully they will step up and get the activity going on the social media accounts.
Thanks @misslasvegas!
