I do not Face Book . I do not Twitter. Ido The Science Forum. But I would like to access NASA. earth science for automatic updates eg., Arctic Ice Melt etc. Their requirement for these updates is /are a twitter Account. You give personal information. What am I worried about here? I do not like the word Personal Account. What does this mean? Account to me means I have to pay somebody some money before I can access their product, in this case, information. Who can, other than the strict Information update Supplier, concern themselves with me.? And what for? I don't want my next door neighbour to know I have a twitter account. I don't want anybody to know I have a Twitter Account. I wouldn't want anybody to know I was on Facebook. Members of The Science Forum might like to give me the low down on any comittments or responsibilites I may be liable to should I join Twitter, seeking updated Earth/ Science information. westwind.
