Hello and welcome from me too, Pineau.
A lot has changed it's true with new ways of doing things. That really surprised me when I returned to sewing 4 years ago. Sadly, there's a great variety in the quality of information, without wishing to sound like a grumpy old woman (but probably failing) there are some fairly new sewers who have set up blogs and are a little too quick to offer their 'little learning' as advice to even newer sewers before they've really got to grips with finer points of the techniques themselves. They often have excellent presentation, promotion and IT skills, however, so it's not always obvious at first.
That's where your old skills will help you cut through the huge mounds of blogs, videos and tutorials to find the wonderful stuff that is also out there. Everyone here is happy to share their own experiences and some very knowledgeable folk with superb sewing skills too, so don't be shy to ask.
