Cool - just needs the Twilight Zone logo and it will be all set. Funny, before seeing this I put on my new year's list to watch the entire Twilight series from the beginning in 2014.
ReplyDeleteUmmm, why men always make lists? =)
ReplyDeleteKeeps us focused, committed, and nostalgic when looking back on things. Generally speaking, all goal oriented people tend to make lists based on something I had read in a magazine years ago. So, that's why... ; )
ReplyDeleteI never make lists...Is boring and just a waste of time since I change my mind daily, plus I'm too moody to follow indications, rules, lists and pretty much everything so I do whatever surfs my brain at the moment.
ReplyDeleteWell, I admitted to making lists, but I never said I follow them completely. It is actually in my nature to be very spontaneous and random. I believe that is what my friends like most about me. I get the sense you do make lists yourself - but they are mental lists because you have an exceptional memory. That would be my bet anyway. ; )
ReplyDeleteI keep a journal. Make a shopping list weekly. And just have a 'to do' list which I try to keep to three items...that's it.
ReplyDeleteGreat pic by the way!
So, we see how light travels, at almost the speed of light! So cool!
ReplyDeleteAs for lists, apparently, they are hardest thing to understand. I love [Ian Tindale]'s comment on my post about List of The Hardest Ideas to Grasp, where he asserts: of all things, now that I think about it, lists really are the most difficult thing to understand, and yet everybody thinks they understand them. What they're understanding is a surface appreciation of them. Once you start thinking about lists further, you'll never come back. Nested lists. Lists that relate to other lists. List items that themselves are relationships. Lists with items that exist in more than one list. Lists that vary across time. Lists that contain things. Lists that leave things out. A list of things that aren't on any list.
Sorry Mindey I. but that comment already annoys me, thank Ra I'm not in the lists business. Probably I'd choke someone if I was.
ReplyDeleteCorina Marinescu indeed... A strategy which would be helpful, is to implement an intelligent agent, which automatically sends inappropriate comments to approval queue, based on the relevance score computed comparing the content of the main article, and the content of the comment.
ReplyDeleteIs not that Mindey I. , the prior comment contains way too many 'lists' words =)
ReplyDeleteHappy New Year Ami Iida! =)
