you should rebrand or something that doesnt use instant! its not a good practice on business if you fail to do what exactly in your domain name, i am subscribe in your system its been 2 months , its quite useful for me atleast after using your service everytime i get a peace of mind that my links will be indexed , maybe faster than the usual way of google indexing rate
but the word instant is not there anymore
maybe it will be more faster to use google webmaster tools for submiting a sitemap and increasing the crawl rate settings
well i hope you fixed the issue about instant! because its not instant anymore i dont know anymore if i will still continue next month or atleast try other like lindexed and compare
