I don't know why but for me Squidoo lenses are very difficult to publish. Each and every article, after writing for an hour, I tried to post there is caught bu its filter as low quality or spam. I have written on many sites and none flagged my articles as such as they do. My first lens which was of not very good quality was published very quickly but after that it has become pain.
The results of my efforts: 1st lens = approved instantly, 2nd = flagged as low quality - edited and edited and deleted content and after 5/6 days tries published with 20% content. I have managed to publish 2 more after trying very hard, but after deleting 80% of content which makes this published lenses nothing but piece of junks. 6 more lenses were deleted by me after being frustrated (never published). What a horrible, horrible thing!
But if you are a lucky guy whose lenses are not always triggering this bloody filter of Squidoo, then it is a nice place. The one and only lens, which I managed to get published with 100% content is doing great and in my estimate if they allow me to publish 20 or 30 lenses there then it would make me more money then 100+ hubs here. Hope that helps, cheers!
