Bobbins Question

Can anyone tell me what difference is in "factory" bobbins and generic bobbins? I took my machine to be cleaned & checked. The tension was funky...every now and again. I was unable to take or pick up the machine as the shop is 4 hours away. DD delivered and picked it up. They told her that not using "factory" bobbin (yes, they used air quotes) can cause issues. HONESTLY? I've never used anything but generic bobbins,and not had problems.

I can understand that you may get a "bad" bobbin, or one that has become warped but....come on! Someone MAKES all of these bobbins, right! Do we really believe that there is a bobbin manufactorer for Janome, and a seperate one for the genenric bobbins?

So this begs the question,was the "use factory bobbins" statement real or meant to sell product? Do you really, really need to use factory bobbins?

Do you Save Yours?

Do you save your posts? I have mine in a file for posterity. But there has to be a better way. I write each entry in blogger. Is that the most efficient method? When my entry is emailed to me I copy it, cut and paste and put it into a Word document. Most efficient?

I totally don't get Picassa and Flickr. I know they are photo storage but I tried to use both and as far as photo storage, I'd rather use Webshots. One of them is tied to blogger and if I try to delete anything from it it tells me that it will delete from my blog (I hope I am remembering right. It was a while ago that I played with these.) I see other blogs with links in their sidebar to pictures....I can't bear the idea of organizing another photo storage (other than on my PC). I want to spend less time on the computer not more.

Any help? How do you do it>
