Unless the domains including numbers have any significance then just the cost of having them registered. The others seem quite generic except for seolearn.info, could probably lead to something quite successful such as a blog or something. So yeah all but one seem quite generic to me.
2070.info 1st time register in 2000 , but i dont know whenever its droped , and now am register it , Freenewsblog, and free freedntalk also have good keywords, and good to manage for business , am planning to manage freedntalk.com for domainnig discussion,
freenewsblog.com - same price you bought or lower.
freedntalk.com - eh, sure dn = domain name, but you could find any abbreviation to mean something if you think long enough. Same price as bought or lower.
seolearn.info - has potential but it's a .info and people could just go get another cool domain like that for reg price and it would be a .com. Maybe same price or higher.
