Well SU works good for latest technologies and tech articles as I have seen it till now. Atleast it will fetch u some visitors for sure..
Dec 2009 my average daily SU was some 100+ SU traffic changes depending on season / day of week, etc never predictable but always some traffic = ONE of many different organic traffic sources On my site I have approximately 40% traffic from SE = 60% organic traffic from NON-SE sources I love that independence from major SE! It shows that there are real alternatives to SE - but G still is main source among the 40% SE traffic of course. On some special occasion days SU brings up to nearly 1000 uv/d - other days just some 40 or so a guess - may be - just may be when ppl are bored and just have some time to kill in the office or at home, they do more SU and when time is critical they may do more SE
yeah but I think they dont provide any api for that... actually its good in a sense else people will start forming group there and stumble each others post even though its not ethical... so no issues with that... its a free bonus as far as I consider
